: Any dyno numbers for a turbo-back exhaust system?

I'm curious as to what the real world numbers look like. What are the hp/tq gains in removing a cat and going from a 3.5-inch system to a 4-inch turbo-back system?

I have before/after plots for my LB7 and LLY systems on my site. LBZ gains actually appear to be slightly less.

Thanks. Looks like for an LLY we're looking at around 12 hp and 25 ft/lb.

Thanks.

Most all Cat back exhaust kits will gain the 10 - 14 RwHp range. If you remove the cat and replace with a front pipe on a LLY you gain a couple more but run the risk of getting a CEL.

"No, I do not require them"



Am I right?
