Well the time has come to put the money down and pick a cat back exhaust for good. Its down to AMS and HKS. Any input you guys have will help, i just wanna make the right decision. How is the sound on both systems? does the usdm HKS system come with an o2 bung or does it require welding? I also heard of it burning the bumper, is that true or not? Any help from some fellow evo owners would help a WHOLE LOT! thanks guys, just tell me what you think is better

AMS

The weld quality is excellent. Bolted right on with a perfect fit, centered in the bumper.
