Y-Pipe or muffler? Which will increase horsepower the most on a stock WS6 exhaust system? Replacing the muffler or changing out the Y-Pipe. Don't have the funds for a complete cat back system.
Also if the muffer was the way to go what would you recommend?
TIA,
Aaron

Re: Y-Pipe or muffler? If I understand your question related to the exhaust system and you have no funds---------I would recommend the Y Pipe because it is cheaper that a catback system. You may could buy a high flowing cat system (SUCH AS RANDOM TECHNOGOLY)/get rid of cat <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> (If possible) and achieve HP and torque gains. However, the cheapest answer to this question is to get a cut-out for track use which is most likely the cheapest avenue for you. Maybe someone with more knowledge with share some light on this subject for you.
Re: Y-Pipe or muffler? I say forget all that. Get a cutout!
My car went 12.07 @ 111 with the stock manifolds, cats & Y-pipe

Re: Y-Pipe or muffler? Why not just leave well enough alone until you can afford a complete cat-back....past experience has taught me not settle for something less than what you want, so I just wait till I have the funds then get EXACTLY what I really want. I just recently put on the Flowmaster American Thunder cat-back after waiting a month till I had the money....I'm glad I waited....the top-end power definitely increased...not to mention the sound <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />
The decision is, of course, ultimately yours...just my $.02

Re: Y-Pipe or muffler? Thanks guys, I realy appreciate the feed back. Sounds like great advice. I'll probably go with a cut out and start saving for the cat back system. Mach Go it's funny the system you mentioned is the same one I've been leaning towards. As soon as I scrape up the money I'll be ordering the American Thunder System. So how was the install?
Thanks again,
Aaron

Re: Y-Pipe or muffler? The install wasn't too bad....however, I took the kit and the car down to my brother's house and we did it in his driveway....the reason being, I wanted it welded up...didn't like the idea of using the clamps...we were able to get a precise fit by welding...he did an AWESOME job by tig welding everything. The only part I didn't want welded was at the Y-pipe...I plan on putting a set of hookers and new Y-pipe on when "cash-flow" allows. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> It was a tight fit and required a little tweakin' to get it right where I wanted it...but then I'm a little ****-retentive about everything being "just right" <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

That run was stock Trans Am exhaust w/cutout open vs. cutout closed. We made three pulls, the first 2 with cutout open, the third with is closed just to see what we'd lose. The third pull dropped from 332 (cutout open) to 318 (cutout closed). Both that car and an '02 Firehawk were dynoed and driven away with the cutout open. They both sounded great and were not really loud at all.

Re: Y-Pipe or muffler? EXCELLENT Shane....that gives me an idea of the gain with the Flowmaster...ran it with just the y-pipe and no exhaust then with the Flowmaster installed....I didn't notice any sound difference...it was just as "noisy" <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> with the muffler installed. I believe the Flowmaster offers very little in restriction. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
Thanks, Jason

Re: Y-Pipe or muffler? No problem, I hang out up at Thunder alot and pick up alot of dyno info... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
