MRT High Flow H pipe ang QTP Cutouts

[athlon551]

Started installing my MRT H Pipe with High flow cats. Welding QTP Electronic CutOuts on it. Just like all of my other projects that I thought was going to be straight forward.....I was wrong again first problem...my floor jack was too tall once I got the 500 on my new Race Ramps.

(Notice the recently fabbed up 2x12. Put spray rubber on bottom so it did not slide)

Just got the old cats and x pipe off and man it is heavy. I bet it will be lighter even with the Cut outs install.

Second snag was the Narrow band sensor :shrug: Green connector??? I got two extensions from MRT but did not count on this one. Should I get an extension for that just for ease to install. Had to wind up the wires pretty good to get this out. The MRT has a bung right where it is but my fat hands cat fit up there where it is connected.



What a bend it the pipe...cant be good for flow on passenger side....

Athlon551,

I am actually interested in exactly this for my 2011. Please keep us posted. I'll be subscribed to this.

Video clips will be awesome!

Seems like a good kit 69mach....only thing I am surprised with is the MRT does not come with hangers as you can see in my pic above. It is also a two piece kit but the H fits so tight I doubt it would leak but I will be welding it this week.

I was going to get the 50's but I go across railroad tracks everyday and did not want anything lower than the rest of the exhaust. Good luck on the welder search.

If you find a better switch setup let me know. Also where are you thinking of putting it?

Boss cant see the rest of your exhaust did you get the MRT h pipe. It looks like you do not have stock x....where are you putting the switch

 

[bossnova3]

My setup consists of the following mostly custom:

Dynatech LT
Customs 3" H-pipe with 3" QTP cutouts
3" to 2.5" resonator to tone it down a bit
2.5" mangaflow cat backs

It took us a long time to get the sound right, but IMO it's civil enough for every day use but nasty when pushed. I'll try to get some pics and post any question let me know.

Ed,

Thanks for getting back to us. Did you install the resonators after the cutout? If so, where did you purchase them. Im soon going to buy the low profile oval cutouts. Part # QTEC66 & the wireless Kit. I want to attempt to have my exhaust shop fab up the "side" pipes that the BOSS kit uses, but im not sure if i should first purchase the resonators.

Any clearance issues with the resonators on? Any pics by chance?

Thanks,
Mark

Pics posted above, IMO I would get the ones I got 3" qtp because they'll give you the most hp. I haven't had any clearance issue, with the exception of the headers and catback I already had everything else was made custom. Don't exactly remember the brand of the resonator but you'll definitely want them on there believe me, I've had more trips to the muffler shop than anyone here but we finally got it dialed in.

Finally got a chance to finish this up. It was way easier to install with the relocated cats.

The MRT H - Pipe definately has a deeper throatier tone than stock. Nothing over the top but that is what the QTP Cut Outs are for.

Drilled a couple holes in the heat shield to tie wrap the wire down and then went into the interior thru the grommets on the rear floorboard then brought it into the center console and wedged it right under the emergency handle. Almost a perfect fit and really cant see it.

Nice work. What filler rod/wire did you use to fuse to MRT's tubing?

I went to tractor supply and bought SS Mig wire $40....not the best but not going to be starred at.

Ah. It was 309L then. I've perused the shelves at my local TS many a time...
