I think this may have already been beaten to death, but the search button isn't working for me. I have a buschur race catback with no resonators on it and it drones pretty loud on the highway. I was wondering if I put a 16 or 18" resonator would it help seize the drone. I don't mind if it doesn't quiet the loudness, but as long as it lowers the drone. I'd appreciate your opinion!

 

Yes it will help the drone go away considerably.

 

It's gonna be loud no matter what. Do you even have cams? If so, it's gonna be even louder with it.

 

Resonator should definitely help the drone. That exhaust is pretty loud, so I would run a larger, muffler, type resonator. Not a
'glass-pack' type. You need a resonator with more interior volume, to me.

 

get a real resonator with actual packing in it. Not something just that is perforated e.g. ebay. Use a magnaflow muffer as a resonator or the ultra-quiet series from vibrant. I personally installed the ebay kind and it did nothing but waste 30 to buy it and 50 to get it welded on.

 

^what he said... perforated won't help much

 

I was thinking of running buschur's bullet muffler somewhere in the midpipe, but I'm not sure if it'll clear the undercarriage space.

 

just run the bullet in place of the test pipe. ive got a few friends who run this way

 

i just ripped my test pipe out and replaced it with a ultimate racing hi-flow cat. it cut my highway drone down alot. it sounds little bit louder than stock.
