Test pipe VS Resinated TP
 

is there any diffrence in power or not really that much? and how much quiter is the resinated one?

i searched and found nothing.

any one?

No difference in power, the sound is basically the sound of having a cat, but still slightly louder.

On the idle it is close to having a cat. But when you get on it, it is louder. But not as loud as a straight pipe. I have the Megan on my car and it works great.
