i plan on getting me a pair, and am looking for reccomendations for install location. i have a mac catted h and slp lm2s, so i am trying to decide whether or not to have the dumps before the cats, or after the cats/before the mufflers. ive got a blower too so backpressure shoulds be much of a factor. which do you think will sound best, and have the best effect? i realize the power gains are small, but i want to try this out as i havent any stangs with this setup.

After the cats & before the muffler of course

I'd just wonder if your want to put it before or after the H, is there room in the exhaust pipe on either side of the H?

with my last catted h pipe there was no room, but mac keeps their cats towards the end of the pipe so i could fit the y pipes right after the headers. i realize it would sound like crap dumping off shorty headers, butwould it make that huge of a difference in performance after the headers or after that cats. hmm itll be loud as **** either way

i just helped my buddy put his on...we did em before the muffler and before the crossover on the H pipe. sounds pretty good i think. he only uses the cutout at the track of course.

so thats basically right after the header, or is that after the h? id think it would sound like crap after the headers, ive cranked it up with the exhaust off and it sounded horrible.

JJ03MustangGT

no it actually sounds pretty good. almost like SLPs i think. its after the header. ill see if i can get some pics today and ill get em up for ya

Flow stills goes through the mufflers a little even when you have then dumps! It will sound better than just striaght headers!

NOT quite....i put my hand up to the exhaust tip when the valve opened and directed it to the cutout. nothin was comin out of the tip. and we didnt use dumps
