question about headers

[mwilson6192]

What ever video you can do I'd appreciate. When it's time to do my car I may give tasca a visit and I'd love to hear it.

And can you give a ballpark figure on what they charge for all that work?


I went to their website and found this video. Looks good but they don't have any vids for 2013-14.

The ballpark figure is $3500 for the Kooks 1-7/8-inch headers, Kooks Green Catted H-pipe, installation and tuning. I had other work performed (see above) which is not included in the ballpark price, so tuning was not broken out separately but was part of the "custom" dyno tuning performed on Tasca's in-house Dynojet and was included in the ballpark price. Header installation is very labor intensive and this price was all encompassing. I had zero desire to install the headers myself, and of course this price includes full warranty from Tasca for the parts and work they performed. If there is ever a problem, I'll call Tasca and they'll take care of it, which is service I'm willing to pay for.

I wish I had a better end to this story than my lame experience, but it is what it is.

All monitors were ready, so I went to the Ford dealer today where I bought my Shelby (a small rural Central New York dealer), and was denied emissions testing. To refresh, NYS exempts the first two model years for emissions testing, and only requires a safety inspection. Since my model year is a 2014, I am exempt from emissions for 2014 and 2015. Next April of 2016, I will require both the "normal" safety inspection and emissions inspection.

I specifically asked to have the Shelby "forced" through the emissions testing anyway, and the dealer said the NYS supplied OBDII device wouldn't even register the car for emissions testing. In other words, the test device would not even run the test after inputting the year of the car being tested because of the two year exemption (which explains why I was only charge $10 instead of the normal $21).

I have no way of knowing whether this feedback was/is true or not, but I didn't openly challenge the service manager. So unfortunately I cannot say for certain that I would have passed NYS emissions testing with LT headers and a high flow catted H pipe, but I can say that all monitors were ready (both the O2 sensor and the O2 heater monitor). My Tasca tune did not turn off any O2 sensors.

I will have to wait another year to find out for certain.

Sorry ...

I'll be waiting for you to report back your results. Enjoy your car this summer.

I guess we will see next year.
Did Tasca at any point caution against the cats at those power levels or for you to limit certain types of driving?
The build looks awesome.

They told me specifically to watch my RPMs (e.g. do not constantly go to redline and do not hit the rev limiter), and don't constantly drag race the car which in their view invites violation of their primary advice of "watch your RPMs". Otherwise, no.

As I have noted in past threads, I have come to understand that I am not the typical GT500 driver, which is the main reason I went ahead with this build. I don't fear a failure of the high-flow cats with the type of driving I do. They could fail tomorrow I suppose, but I was comfortable enough to go ahead with the modifications. As they say, YMMV.

If your test is anything like our test in NH, as long as all monitors are passed and the CEL is off it will be fine. As long as the inspector sees something that looks like a cat it's fine, and that's only if they care that you have or don't have one. Nobody's going to check beyond that, it's a waste of their time, state inspections are a flat rate. You probably didn't have to go through all the trouble that you went through for this, though it made for a very informative thread

Resurrecting an old thread. There was excellent discussion in this thread that got "deeper" into the question of "Is there a product/combination that offered long tube headers with catalytic convertors (cats) that maintained COT protection strategy; maintained the ability to handle the horsepower of modded late model Shelby's (particularly 13-14 GT500's); had the duty cycles to enable the cats to "live"; had EPA or CARB certifications; and could pass state inspections (excepting California and specifically could pass New York State emissions).

Several vendors weighed in on this conversation with both pro and con comments/viewpoints.

I personally held off on installing exhaust modifications because there was no way at that time to pass New York State (NYS) emissions.

Fast forward to today. I had a large number of performance modifications installed on my 2014 GT500 'vert by Tasca Modshop out of Cranston, Rhode Island in Q4 2013. Tasca has spent time developing an exhaust modification package that they claim will meet NYS emissions, as well as New Jersey emissions, Connecticut emissions and Rhode Island emissions - all of which are now purportedly identical to NYS emissions. I have been assured that this exhaust package will pass these states emissions inspections without any further effort on the owners part.

Because this is a topic that has been discussed multiple times and has generated quite a bit of interest for those folks who live in the above states, I thought I would volunteer my experiences with this modification. I have chosen to go ahead with this modification based upon the assurances of Tasca Modshop. Please understand I am not trying to sway anyone's opinion, nor am I trying to promote Tasca Modshop or Kooks products, nor am I trying to do anything other than share my experiences with headers with aftermarket cats passing NYS emissions, and how my modded Shelby works with these exhaust modifications.

Specifically, I am having the following modifications performed:

• Kooks 1-7/8-inch Long Tube Headers
• Kooks Green catted H-pipe (Kooks Green catted X-pipe is "standard", but I opted for an H-Pipe)
• 3.75-inch supercharger pulley replacing my current 4.00-inch pulley on a Whipple 4.0L polished supercharger
• Larger Carbon Fiber cold air induction intake with billet MAF flange replacing a Whipple 123MM CAI kit
• Whipple Big Bore Throttle Body and Adaptor replacing a Ford Racing CobraJet Monoblade throttle body
• Custom Tasca tune with dyno calibration time
• To accommodate the modifications, the Tasca tune will limit red line at 6450RPM versus my current 7000RPM red line limit

I have an expectation based upon earlier performance mods that my RWHP will be over 800HP (currently is at 760), crank HP will be over 950HP, and torque I'm not quite certain (I was at 666 but this should push to well over 700).

This thread generated much previous discussion about Kooks Green cats, focusing on CARB certification (they are not), EPA registered (they are), longevity under high horsepower applications (some say they will be fine but most seem to believe they will not be fine), and COT protection strategy for any catted application. Tasca developed the above exhaust modification package with an associated tune and has assured me that this combination will pass NY, NJ, CT and RI emissions inspections. Tasca further specifically enables/preserves COT protection strategy in their tune.

I understand that there are dissenting opinions/observations that this exhaust option is not a tenable/viable situation. We shall see as I have become comfortable enough to proceed forward, and as I noted above I thought I would share my experiences with this community, and hopefully this will be of benefit to some.

I will be submitting my 2014 GT500 to Tasca shortly and should have my car returned to me in roughly a month's time. My NYS inspection is due in April 2015, so I'll have a report on passage at that time.

I'll update this thread occasionally with my experiences.

Do you know who you spoke with at Tasca about this? I am just rebuilding my engine and hoping to be done in August, and will have the Kooks long tube and green cat combo. If I can get a yes we have had this package work and pass emissions on cars in NYS than that would certainly set my mind at ease.

If you check my previous post in this thread (http://www.svtperformance.com/forum...ut-headers&p=14827084&viewfull=1#post14827084), you will note that I was not able to actually go through the NYS Emissions Test because my model year is in the final year of emissions exemptions (or so the dealer insisted). So, I don't have a firm answer for New York State ... yet.

The gentleman who worked on my car at Tasca Modshop is Dennis Gomes, and he can tell you directly what cars he has personally tuned and passed specific state inspections. Tasca has stated that their configuration will pass NY, NJ, CT and RI state inspections. I will say that the O2 monitors and O2 heater monitors became "ready" just as he insisted they would. Tasca does not "turn off" any O2 sensors, and all COT strategies remain in place (in short, my car has perfect drivability and street manners with Kooks headers and Kooks Green cats with H-pipe).

 

[mwilson6192]

Hello again. It has been another year (they go by far too quickly these days). As promised, I am updating this thread with my experiences.

I took my Shelby with the previously identified modifications to my dealer where I purchased my Shelby to submit it for my first New York State (NYS) full emissions test. Before I took it there, I double checked all of the IM monitors, and all were ready (just like Tasca promised). The results?

IT PASSED WITH FLYING COLORS without doing a thing to prepare for the inspection!

I can say factually that my modified Shelby passed a NYS emissions inspection with Kooks long tube headers, Kooks Green catted H-pipe, and all of the other modifications I listed earlier in this thread without incident. To date I have had zero issues with the Kooks headers or the Kooks catted H-pipe.

Please understand this is not an endorsement for Tasca nor Kooks products. I simply wanted to share my experiences with NYS emissions with aftermarket headers and cats, and it is possible to pass NYS emissions testing (and other similar state inspections) based on the merit of the engineering that went into this particular combination.

 

[BrunotheBoxer]

Most impressive. I guess tasca would be where I would go to get work done as they are real close to me.

mwilson6192 im guessing your Shelby has been living happily at 842whp.

Yes sir! No issues, full street drivability and manners, and power when I ask for it.

That's awesome man. I haven't had my car on the dyno but I'm guessing close to 800whp. But I'm pretty easy on my car.

Drudging this one up from the past, but anyone have similar success with the SW LT's and their catted h-pipe? I've got a solid tuner, but at the moment the last 2 monitors won't go ready, O2 and O2 heater on a catless h-pipe.

I ended up getting collector car insurance on my car so I didn't have to worry about emissions, maybe that's a option in your state?

Nvm, sry

Not exactly. If you drive your car less than 12k per each 2 year renewal, you can request to be emission exempt. I would easily qualify, however the car came from NC and is new to Missouri, so it has to have that first test. I have the OEM exhaust, but would rather not go through that headache.

Same here, its nice only going to inspection every 5 years
