Hello all, I got my g37s coupe about a month ago and am now starting to begin the slow process of modding..
I just recently bought the gen3 intakes and now am wondering if I should go with the ark exhaust and the intakes or get some test pipes instead with a tune..which will get me more gains??
I also need the car to sound louder..the stock set up is too quite..will the test pipes get me some more sound?? Or would I need the full exhaust to get what I'm looking for??

Any help will be greatly appreciated and sorry for being such a dumbass newbie lol

 

I say go for a cat back exhaust, but not the ARK...
Test pipes+y-pipe with a dyno tune will probably yield the most power though.
