HHR 2.2 down pipe no cat
I own a 2009 HHR Panel with headers and a catback exhaust (GM) but still has the catalic installed.
I was wondering if anyone has installed a straight down pipe without the cat, is it loud and does it give the 2.2 some extra ponies.
Does the ZZP down pipe for cobalt would fit on the automatic HHR.
