If I remove my resonator will it affect my car's performance?

I have a 2009 Honda civic si, and I put a 2 3/4 inch pipe starting from the catalytic converter all the way to the muffler so the resonator got removed, will it only affect the sound or did my car loose horse power or does it affect the performance in any kind of way?

Probably will just hurt performance a bit.

Why did you hack up your exhaust?

It didn't have that much power to start with.

I don't believe it will affect the performance all that much. The back pressure loss would be minimal.

Yes it will drastically affect the performance.
A work colleague had his removed temporarily while waiting for a replacement. He said the car was terrible to drive.
Honda have very cleaver people. Leave it alone.

  • Will the ecm affect my smog test? I think my ecm is bad in my 96 Honda civic ex 5speed. Can I change the ecm? Do I need to find the exact matching ecm or can I use a different year ecm?

It's hard to find exact match that's why I want to know if it matters also I gotta smog test pretty soon.

  • Can I upgrade hybrid car performance w/ losing hybrid properties? I have a 2005 Honda civic hybrid. Can I customize parts components electronics everything. And still have hybrid mileage?
