HELLO I'm looking for a stock h pipe for my 11 gt500 I'm located in Los Angeles.
I had someone selling an h pipe near me for 200 bucks near me I just got to the deal a few hours too late, the 13-14 H pipe is 3" inches I have a 3" inch X pipe on mine with high flow cats that I really hate; it doesn't sound good in my opinion and the fumes I'm not willing to put up with them anymore since after 2k miles are failing. Also this is my second gt500 the first one is the one in my profile and it doesn't have have the power as the first one and I'm looking for the power loss somewhere I had changed multiple items on it, I believe with the bigger exhaust it losses torque to a ridiculous level in my opinion but then my car has 110k and I doubt it has any engine power loss it still puts down 485 hp with 474 torque on a dynojet, I know a lot of gt500's put those numbers down fairly new I guess depending on altitude and conditions.
