RE: exhaust question
Yes, there are "off road" X and H pipes available from Corsa and just about every other manufacturer that delete the cat. Generally, on anything close to a stock engine deleting the cats will reduce low end torque a bit and won't increase HP.
There are a wide variety of exhausts available and in use and the greatest difference is in the sound. Resonance (unwanted) is a major issue with many. I would recommend buying for the sound as the power added by a cat back is minor not enough to notice. Long-tube headers, on the other hand, really wake up an LS1, LS2 or LS6 engine. |
RE: exhaust question
but what about the cel? that is really my only concern

CEL?

Check Engine Light. cel.

RE: exhaust question
Okay, just be aware that most three letter acronyms have dozens of meanings (CEL:Combustion Exhaust Limit/Carbon Exchange Laminate, and so forth). Best to be clear by spelling it out.
Generally one has the ECM reprogrammed when any large mod is made. You can also substitute O2 sensors replacements (dummies) that trick the system into staying in a stable mode, but they work best when the ECM is reprogrammed, anyway: they just make it all work better. Any good tuner shop can do this. Any bad one can really screw things up, though, so do some reserach on who is good locally. But you can probably get by with a cat-back exhaust without a re-tune. Headers, though, and you have to have one. |
