Hi all

Got to build a new exhaust system for my triller, system that was on it was quite nasty but worked so i left it but the tin work has eaten it beyond repair

Its got a 3.9 in it

Any one suggest best exhaust diameter for primaries + after it joins to 1?

I was thinking 1.75" then 2.5 or 3"

Cheers all

James

Would not go any bigger than 2.5 on the 3.9. Either 2.25 or 2.5 are reasonable, definitely not below 2.0
