^ x2... Not much..

It looks like it bolts right up after the cats. Call SLP and ask. If you're in Cali, this may be all you can do and I'd say go for it.. But otherwise save for some LT's.

When I got my first LS1 car in 2001, I put the SLP y-pipe on and I noticed absolutely no difference in power. Save money and put headers and a y-pipe on.
