do any of you use the car chemistry headder inserts. i am interested in the 3 ring street/strip one and i was wondering about the sound. ?

dosent anyone run theese?

okay after talking to a custom street rod building shop who has used this product 6 times and all 6 of his clients he built rod,s for got ticket with the 3 ring insert . theese product,s do not make your exhaust quiet enough for the street to be legal f y i incase anyone else considers using this product.

Thanks for the info. I figured they would be pretty loud. I even wonder if they would pass strip regs.

They're too loud to be run without mufflers. And they're too restrictive in a high HP application. Had so much back pressure with my yellow Camaro it bent the baffles when I went full throttle.
