Picked up a badmab header a while back and im considering a zzp 2.5in catless dp. I know its going to be alot louder, but im wondering if it will cause my exhaust to sound raspy. I can deal with louder, just want to keep the same tone.

 

i am running vibrant 4-2-1 header and catless dp with gmpp "race" exhaust and its loud but i like the way it sounds

 

i think its best if you get the 2.5 dp catted and the tone will remain, it'll just be a bit louder imo

 

Stay catted. You will need the back pressure

 

Just emailed zzp to see if I could get the spun metal cat instead of ceramic core with that dp...

 

Don't go catless. It sounds terrible.
