Does anyone know how much a stock 2001 ls1 would put down? I am sure its probably posted somewhere, but I couldnt find it...

Anyone know what the vette may put down with corsa indy exhaust?

 

I believe 2001s at the engine were 350 hp and 375 tq. I think a catback would add about 7-10 hp is all. WHP is going to depend on several things so that is very hard to say exactly. I would say around 315-318 hp.

 

That's about right, depending upon the correction type and dyno. SAE-corrected, my 01 (stock) put down 308 RWHP. With intake and cat-back, that's up to about 320 (SAE) and 328 (STD-correction) on a Dynojet. I believe the cat-back adds only a couple of RWHP, unless the engine is heavily modified.
