Shoot us a PM and we can get you a price!

Hey Rich, I had my AFE catback installed 3 days ago however when cruising 60-70-80 m/h drowning comes. Do you suggest anything? Any resonators I should buy?
Thanks,

Thanks,

New exhausts can take a while to "Season". You'll get a slight carbon buildup on the inside of the pipes which will help dampen the droning a little bit.

I would wait a few weeks before deciding if you need a resonator. The sound usually does mellow a bit.

Ok, good. Thanks Rich. I have it installed as per manufacture on/with clamps, however I was told that if welded would be better. Do you suggest welding instead and why?

If the exhaust specifies clamps, clamps will work just fine. Welding isn't going to change anything unless you've got an exhaust leak.

I wouldn't weld an aftermarket exhaust to your OEM if you ever plan on selling the system either.
