I know the midpipe voids the warr but does the super cat void the warr also on the car,

RX-Hawk

Nothing "voids" a warranty.

Red Devil

Neither will void your warranty unless the dealership could prove the problem you would be having with the car was directly related to that part. While your powertrain warranty *could* come into question, your suspension would still be covered.

Either are illegal due to EPA regulations. But some members have passed emissions with the Supercat.

ok thank u because i was going to order the midpipe this week to go on my Greddy Exhaust System

scsi

will the midpipe (no cat or resonator) give same or better results power wise as the supercat? will you get a CEL?

Does the 3" Midpipe Fit on the Greddy Exhaust Cat Back System..OK

Fanman

Maybe a hp or 2 on an NA car, but nothing noticeable. It might very well throw a CEL (about 60% chance), whereas the hi-flow cat will not, and you will pass emissions.

Fanman

If you have the Greddy, you do know that putting a midpipe on will make this ridiculously loud right ? At least with a hi-flow cat it acts as a natural resonator and cancels out some noise, but a straight midpipe and prepare for ears bleeding & cops pulling you over.

well i see by next week when i get and put it on my car b/c some people says it loud and some people like it so i see how i will like it

It will be very loud when you first put it on, but quiet down over time.

Midpipe vs. HF cat and gas mileage? Any thoughts? I searched but couldn't find anything...

mysql101

I don't see any reason for it to change your fuel mileage. Mine hasn't changed since I put on a catless midpipe.

foxman

cool, thanks
