S-Pipe Constraint?

Hello,

My 94 Z28 has edelbrok headers and y pipe, a 3" high flow cat and a 3" SLP 2OTL catback (mostly). The problem may be that my S-Pipe is stock 2.75.

How much would this hurt performance?

I am working on the process of elimination to get this thing running right.

Re: S-Pipe Constraint?

The performance loss is probably negligable. I wouldnt worry about it. On bolt on cars, there really isnt even much of a power difference between cars with 3 inch catbacks, and those with just mufflers.

If youre really worried about extracting every last bit of hp out of the engine, throw a cut out on there.
