ok so this is everything im buying for my 09 cobalt ss turbocharged.
3 inch cat back exhaust
a hi-flow air intake pipe
charge piping
and i dont know should i buy a new blow off valve or not? what do you all think keep the factory one or not.
if you say get a new one what will it do better than the factory bov?
now my question is i need some sites where to get this. and dont say hahn cuz theres i think is seriously overpriced
for my exhaust im going to get it off of www.modernperformance.com
my air intake from www.dejonpowerhouse.com
now my charge piping i cant find a good somewhat cheep site to get it
modernperformance has one for about 450 hahn has it for 500 is there any other sites that i could maybe get it cheaper?
and if you could think of any other mods i could add besides an intercooler and a downpipe would be nice toknow?

 

Excluding Hahn:

For downpipes and chargepipes, I'd look at maybe Clear Image Automotive. They make great downpipes and chargepipes and I've been super happy with mine. It sounds like it's also in your price range. ZZP, Injen, and GenuineSaab makes some, and now MP makes them too.

For catback, I'd now look at Modern Performance. CIA makes one with a few options, but I haven't heard much positive stuff about it.

For intake, I'd honestly just put a K&N Drop-in in. You'll thank yourself later due to the problems often caused by the current intake options.

As far as a BOV, I'd personally not recommend it until you do a turbo swap or something. It will throw off your engine air-fuel mixture every time it pops off.

As far as bolt-ons that pretty much covers it... the whole path of the air... intake, hot side charge pipe, IC, cold side charge pipe, downpipe, and catback. We don't have intake or exhaust manifold options at this time, but then again you're moving away from bolt-ons by that point.
