The performance of this product exceeds my expectations. Sounds great and works great! However, it doesn't look or smell as good until all the Norustavil paint has burned off. I didn't know the paint would burn off and I'm very disappointed with that. It was a shame to drive with smoke under the hood and the paint burned out. People thought it was overheating and it smelled really bad at the time. I'm not upset with its looks as much as creating a custom "look" under the hood. If you want a custom look you can always paint them with heat resistant paint (any color), but I won't do a custom look under the hood because it will get dirty anyway ;) RHEC Yee-Yee!
