when running turbo should your exhaust (cat back) be the same size piping as your downpipe? most exhaust systems i've seen are 2.25 inch or so and i'm just curious. going to be using a 2.5 inch DP.

 

no one?

 

yes that creates unnecessary back pressure. They make 2.5 exhaust. Search harder or build your own

 

cool. just a question for anyone who's had a custom exhaust made: how much does it cost? my welding skills are literallly non existant so i'd probably have one custom fabbed. or if there is anyone in the LA area that woul dbe willing weld one up for decent pay PM me.
