Does anyone know the diameter of the Comptech Catback Exhaust system?
Are they 3'' like the Greddy or smaller.

Thanks~

 

Are you referring to the tips or the exhaust piping size b/c the Greddy exhaust is not 3". The Greddy exhaust is 60-70mm which means in some areas the exhaust is 2 3/8" and other areas are 2.5" The tip is 115mm which means it's a little over 4.5" The Comptech exhaust I believe, but I have to double check, that the B-Pipe is 2.5" and then the axlebacks are 2 3/8" for a short area and then flare out to 2.5" but I have to check again withi Comptech.

 

I'd go with Comptech not being bias or anything but they are not loud and have a nice tone to them. Greddy tend to get loud at WOT.
