Which is better

[KORNFED_DIRTY D]

IM debating whether or not to get a full exhaust for my ej1 or not. its a boosted d, and right now I have open downpipe. plese feel free to give me your inputs, thanks!

I would imagine you should... you're car would run much better with a bigger exhaust since you're running boost.

I can't imagine that's very good to run your car downpipe-back... just sayin.

open downpipe is so loud lol I had to do that for about 40 miles once to my mechanic and I couldn't stand it.

Get a good cat-back...
