Catback Exhaust plus X-Pipe?
I posted this over on the Corvette Forum also. I know most everybody here is on there as well. My 1990 is chipped but stock otherwise. If/when I add a 3" Catback system w/X-Pipe do I need to have my chip updated from Marc? Thanks.

Re: Catback Exhaust plus X-Pipe?
Yes, talking to Todd but even if I don't get his I am doing the exhaust in the near future. Will be keeping the cats at this point, not doing headers yet. Going to build in steps so I can actually catalog the power increases.
1. Catback w/X-Pipe. 2. Headers minus Cats. 3. Intake Porting. 4. Intake Cams w/head porting. Will also do 4.10 gears in there somewhere and I will do the required updates to the Chip as needed. Craig, |

Re: Catback Exhaust plus X-Pipe?
If thats the case for step 1 Then the answer to your question is No. when you hit 2 3 4 yes you will need to mod the chip

Re: Catback Exhaust plus X-Pipe?
Not to hijack a thread, but I've been wondering about this same question also. I am considering doing headers when I replace the exhaust to save labor. I'm looking at the same mods as the OP and also in phases.
I'm getting some back fires now, so I figured a reflash would be part of the process. I also have 93 octane here so that may be something I can include in a reflash.

Re: Catback Exhaust plus X-Pipe?
Thanks for the info guys. Does anybody have a sound clip of a B&B exhaust on their ZR-1? Not crucial to anything, just thought I would ask.

Re: Catback Exhaust plus X-Pipe?
Hey on second thought, what if I was to go ahead and delete the Cats now? Stock manifolds with cats deleted? Reflash the chip? More importantly is there any benefit powerwise without the headers?
