Custom Straight Through De-Cat... Help!

Post by MadManMike »

Right, i'm getting a custom pipe made, but I need to know the diameter of the pipe that runs to the back box... I'm gonna get a 3 or 4" tailpipe with a straight through pipe... what diameter is it?

Standard bore is 1 3/4". You wan't two silencers or it will be too loud. You might wan't to consider 2" if you are doing a fair bit of engine work.
