Ok. Recently, I've been noticing whenever the car started up, it sounded....LOUD. I thought it was normat till one my co-workers came along on ride to search for a part today. He mentioned it sounded like I had a catless dp. It sounds exactly like this guys car in the vid:

Will this void my warranty? Is there a way to check it the car has been tuned before without having a dealership check it???

no, it wont void your warranty.. nex time you're cruisin an got some space, mash the gas an see what your boost gauge reads, if it's higher than 14psi, with (cruise control or traction off) you're tuned

Never went over 14 psi. Hit 15 psi once because of the weather one time, but no matter hard i floor it...it doesn't go over. How much does the stock dp cost to get? Just in case I need it to pass MD inspection.

Why dont you just look under the car to see what you have? Would take like 45 seconds with the time required to jack up the car. If you dont know, snap a picture of the downpipe post it on here and ill tell you.

get under your car and look at the DP and see if it's catless or not?

just post up a want ad on here, I'm sure somebody will want to get rid of their stocker since most get catless anyways. certainly sounds like catless, and stock boost is 15 psi. If you're not going over that then you're stock tuned.

Sounds catless to me judging by the turbo spool sound at idle. If you blip the throttle a bit around 3k and it sounds like a gunshot went off out the back then it's definitely catless or if you NLS.
