Almost enough to make the sound you hear=the ***** you think your car now has.

20-30rwhp with a lid or CAI.

can be even more with a tune...if your wanting to know if you will feel the difference..yes you will..

i have a 99 SS M6 and i went with pacesetter longtubes with a custom y-pipe thru the stock catback and i made pretty good numbers. when it was stock she made 297/308....not too impressive, but once the longtubes and lid went on, she made 333/338. after i got a tune, she put down 352/360.... and this was thru the stock catback. thats a 55rwhp/52rwtq gain! i never had a chance to see what she would do with the cutouts open. oh yea, all my runs from stock to now have all been on the same dyno too. you will feel a difference, especially down low.

25 to 35 hp. The sound will change quite a bit also.

LOUD... That's what i'm talking about..

Would you guys suggest the y pipe or true duals IF you are planning to lower your car?

And what will be the difference in terms of the h/p.(between truedual and y pipe + catback.)
