I have an ej1. I plan on running 2.5" piping (kteller). I also wanted to use the hks hyper. It has a 60mm inlet which is 2.36". Would that cause a problem with exhaust flow? Do you think I should run 2.25" piping instead?

 

go 2.25 unless your running a lot of power then get the 2.5 i guess

 

i have a dc sports catback and its 2.25 and its awesome and sounds great

 

okay...well the reason i wanted to run 2.5 was because i am throwin on a small turbo..and full 3" is not an option

 

keep it at least 2.5 if youre gonna turbo your car, but as far as your exhaust system, id look into another muffler

Yes. If you're gonna go with 2.5" exhuast piping, get a muffler that's at least 2.5" as well.

 

if you want that "jdm" n1 endurance style muffler look into the apexi n1 universal muffler that has a 80mm inlet

 

Just buy any muffler of kteller as well...
