exhaust cone
Another excellent product from ZZP quick shipping very well made and hard to believe a simple item like this does what it does but the difference was amazing the repair shop welded it into the Magnaflow catback on my HHR which was way too loud & there was an immediate improvement lowered the volume considerably and also got rid of the annoying drone at a certain rpm I'd highly recommend this product

Nice
Nice craftsmanship but did not make much difference in loudness even with two installed.
