you have a 2008. thats more or less why. but i can't stand it when people say don't put a DP on you car or test pipe cause you'll blow your turbo seals. for some reason 2007's got a big bach of turbos that were sent out with crappy seals. i've only seen turbo's replaced on 2007's maybe 1 2008 but i guess 08's like mine YAY don't really have the turbo problems that i know of. i just hate it when people post on here and say their DP's or test pipes cause their turbo failure this is so false and total BS your turbo was going up before you put the DP or test pipe on there.
the only difference is because you took off the so called filters for the exhaust you can see it alot more easy now, DP and test don't cause turbo failure bottom line me personally i'd rather put a DP on my car before my warranty goes up so i know if my turbo is bad and have a new one put on under warranty then wait and find out later and have to buy one myself. just my 2 cents but thats good news for you. i should be getting my test pipe this weekend and can't wait to install it.
