Yeah idk about that thing, I guess in a residential area its good... I'm wanting that Isis dual tip straight pipe I hate the "street bike" canister on most catbacks plus the Isis straight pipe sounds beastly. Yeah and Martin all the way. 200-220 to the wheel shouldn't be too hard to achieve. I might be buying a S13 T25 to resell so you should keep an eye out for that FS thread, it wont be no overcharged T25 either like you see on TR
