Doing a 2.5 " custom exhaust setup for a friend and I only see that the Apexi n1 comes in either 60mm or 80mm, which size n1 should I get for a N/A gsr 60 or 80mm?

 

60mm, most N/A setups go with 2 1/4" piping and most turbo guys run 3".

 

I know but I'm thinkin more into the future for friend incase he does a mild all motor setup. My self I'm doing 3", but the question is would it be easier to weld either the 60mm to the 2.5" piping or 80mm muffler to the 2.5 pipe?

 

i had the same question

 

ANyone knows? I swore there were alot of welders on here .
