Ok folks-

so i have a 95 12 valve cummins- it has the 4" turbo back straight pipe now- with no tip.

I was offered $150 for the system or $75 for just the down pipe and i could sell the rest elsewhere.

So- i'm debating going with the 5" straight pipe with a 7" tip..

4" just doesn't seem loud enough- but the 5" is $325 + an $80 tip.



Anyone have thoughts on the 5"- i know theres a few cummins guys here.

Sell and upgrade or keep and put a monster tip on the 4 inch? :p:D
