if you want to hear the dv more get an intake. as for the test pipe, i would recommend it. i got a testpipe and a 2.5 inch exhaust that uses borla mufflers (its from techtonics and a much better choice than a borla system if your gona upgrade the turbo at any point in the future) the testpipe will improve power much more than an exhaust system will. but if you have emissions in your state, your screwed because they are illegal.

 

LOL ^^

If you have emisions you might not want to get the test pipe. And yes chipping the car and doing the box mod will make it louder. Welcome to AF.

 

o and only a shady body shop will put it on cuz there's a $10,000 fine for removing the cat. or you could just put it on yourself like i did

 

if your fiated on the bov you can move your maf to the other side( put it like right before your TB) and you should be good to go. I've comtinplated this, not cause i want a BOV but because i wonder if it would work. but im to lazy to try it
