Just put on a HKS hi power exhaust..soon to get a downpipe and uppipe...any suggestions on which ones?...(stock turbo)... cutting resonator..opinions? concerning sound power?
I have the helix catted DP on my car with the Perrin cat back... Sounds great. The helix DP was a work of art. I felt bad putting it on the car. Even my wife was like wow thats pretty !
i have a turbo xs dp on my sti. the only bad thing about it , i have to get protuned because i hit cel. the dp dosen't come with a cat.the turbo xs is 4inch and tapers down to 3inch.but i love it!!!!!!!!!!!!!!!
I have a Perrin DWG DP NEW in box if interested PM me p.s. will trade for catback (tame kind) or Nokian WR (tires)
I like my Stromung shorty. I plan to get the high flow mid soon. The divorced wastegate pipe makes everything sound so much better under the hood.
well..i was told that the hks dp and up is good for stock turbo.. and its great for the price. i don't know..just want to throw in an up and dp.. so it will be cat. less.
