are u guys running resonators? I have some cheap no name brand i think.... but i think it might be causing me to loose power. I heard the RSR resonator works good. Any ideas? comments? TIA

 

I would say if your running a good hiflow cat with 2-1/4 or 2-1/2 inch pipe, dont worry about having a resonator. If you run no cat obd1 style, get a good 2 foot long resonator. It will quiet the exhaust down and help keep a decent amount of back pressure.
