Stillen headers / hi flow cats

Berks are 200 cell count and have proven to not fall apart. The Motordyne XYZ y pipe is just that, a Y pipe that gives you the option to run either straight pipe, resonated or with a HFC. Unfortunately, it's not compatable with your exhaust. If you had an exhaust that used the same mount points as stock and is a Y pipe design, it would be G2G. I second PPE's if you want the best. The Momentums are the only shorty I would buy. If you are dead set on having headers, want to keep your existing exhaust, and run HFC's, buy the Z1 (Momentum) headers and HFC.while you are at it, just buy their whole power mod and call it a day. You will get a healthy increase in power. Just don't say we didn't warn you on the install, it's terrible and cost of labor is running about $800.
