so i keep hearing all about this dreaded "resonance". what exactly is that? i just installed my xs headers and there is noticeable vibration on the gas pedal at low RPMs on all gears. is this normal?

also on a separate note, i hear that alot of thieves like to steal cat converters and sell them for money. i took out my stock cat. converter.. what kind of place would buy it? how much cash can i expect when i sell it?

 

you just got a PM about that stock cat.

 

anywho..


some do come out a tad bit on the not so perfect side from the warehouse.
i have a tad resonance when i pass 2.5K but now.. for some reason. its gone. haha

vibrations, i've never had.. mine feels a bit stiffer.. thats all.

 

resonance sounds like a a bee in a tin can or a weedwacker hitting a metal fence. I never had it for the first 5 years and suddenly in the past few months it started. Usually wrapping your flex pipe with an exhaust wrap take away 90% of it.
As for the vibrations, I have no idea what that is from.
