pros/cons off road H-pipe vs catted H-pipe?

 

[white88lx]

in my opinion the technology is so good that with cats with you dont loose noticeable power so the real difference between them is the tone that you get from the exhaust. Also depending on how much performance you are going for and the amount of drag racing with race gas and etc you may go thru cats quicker than you would like too. my .02 is just save the headaches and go with off road, sounds bad ass and dont have to worry about burning ur cats if you have a 2 step and wot and run race gas.

also have to acknowledge the fact that depending on the state emmisions may be more strict on visibility

Thanks for the response. What companies make an off-road h-pipe for 2011-2012 GT500? Recommendations?

I am aware of MBRP. I can't see that MRT does it for a 2011.

Cats clog with high output engines. You can also run C16 mix with the NC pipes.

I got mine at Mustang Racing Technologies and really love the sound and the product was good quality. They were easy to work with on the phone.

Here is the link: Mustang GT MRT H-Pipe Exhaust, 2005-2010, without Cats - MaxFlow Series - MRT Direct

I'm running this along with several others. Never heard anything bad about them.

Appreciate the response. Will the MRT or PHRP pipe fit the 2011 due to the changes in exhaust vs the 2010 model. I didn't think they would fit.

I bought the MBRP H-pipe w/Cats. Hope to install this week. I think my choice is pretty solid considering all the posts out there.:banana:

People seem to have a hard time finding an exhaust sound they like with a catless pipe...that's about the only downside. If you are near stock, cats are fine.

It's an easy fix to tone down the noise with o/r pipe. Add a 2nd pair of mufflers or add resonnators on the catback that way you won't lose any flow but tone it down.

Thanks for the feedback.

Engine is stock currently. Planning on tune/pulley at a minimum but leaning towards TVS.

I have roush axelbacks today. They sound good and are pretty loud for just an axelback. I like the sound most of the time but don't care for the "glass pack" sound at 3/4-WOT. Just not my preference.

So I am trying to keep the same volume if not increase it a bit but get rid of the glass pack sound.

Being new to this stuff, from what I have read a larger aftermarket H-pipe would help along with a chambered muffler.

I just don't know if a catted H with a chambered muffler will give me the volume or if an offroad will be too much.

Then there is the issue of finding an axelback that will fit a 3inch aftermarket H pipe. Otherwise mods will be needed to get it to fit most axelbacks.

Thanks

JBA makes a 3" system. I'm running their 3" offroad system (x-pipe) and when I get my car back from the failed alternator, I'll make a sound clip. I have a set of used SVT-1 mufflers that I may try but I'll just need a muffler shop to put a 3" inlet on them.
