sold: 1999 firebird- 1998 Trans Am
no i definatly meant front wheel horsepower, i have a rare experimental trans am that was built in japan.
and we like to say all ls1s have 350 horses, but i am one of few who disagree. i think irl if you bought a 100 new t/a's (completely unmodded), and put them all on a dyno you would discover 95% of them have 320-340 at the crank. especially being we are not talking about an '01 or an '02 (the best performing years for f-bodies)
OP's nemesis probably has a driven and enjoyed 80k+ car with some wear and tear. mild mods such as a tb spacer and exhaust would fairly give him about 350horses

I like the way the factory exhaust sounds. I also like the idea of the cutout. How much of a difference would that make in the sound and performance if I put the cutout before the cats?

It would require cutouts and stock there is no way you are doing it before cats since the cats hook up directly to the exhaust manifolds. Stock exhaust with a cut out you aren't really going to hear an awesome difference if anything the sound kind of sucks-but it flows better. A single cutout before the muffler will suffice. If you want to bypass cats with stock exhaust manifolds get an off road y-pipe.

How much HP do you really think your getting by having a cut-out? All your getting is a louder exhaust and poor performance. The computer needs to be tuned to run right with an open exhaust or it will be flat. With all the work that I have into my SS, LT, ORY, cam....., I ended up swapping out the LM1 exhaust for a SLP SS exhaust and ended being the best move I've made. Not only does it sound better (no more rasp) but it runs better too. Just by giving it some back pressure, it pulls a little harder then before. Save your money and do a good cat back , CAI and and PCM tune, you'll be much happier. Look for a good deal on a used SLP SS or Firehawk Exhaust and stay away from the SLP LM1 for a daily driver

2002 Z28 A4 NBM- Sadly now demodded :(
I beg to differ. On my 02 with an otherwise stock everything and just the addition of a cutout in the I-pipe (the 1st mod I did) I dynoed at +15rwhp and +19rwt over the stock dyno results (306rwhp/323rwt stock). This was the biggest gain with this particular mod.
The more I modded the exhaust (LT's, !cats and AIR with a 3" custom Y-pipe) up to the point of going with TD's and an X-pipe (at which point I ditched the cutout) the less effect it had on the dyno. Prior to the TD's (but with LT's and other deletes + a lid) the difference was only 2rwhp/3rwt. Still technically a gain but not as much (nor as noticeable) at the track on ET and MPH.Last edited by 67CamaroRSSS; 02-26-2010 at 06:16 PM. Reason: spelling
