16723 MF Cat-Back for 4th Gen LS Firebird
I purchased the 16723 cat-back for my 4th gen Trans Am. Quality and fitment were great with only a little shortening needed for my ARH Y-pipe and headers. All the pipes slipped together well. It clears my MWC 9" rear end. This is a street exhaust for people who want to be able to have conversations in their car, not wake up their neighbors. I recommend taking your time when installing this; to get best the fitment and ground clearance you will need to support the lowest portions of the exhaust while tightening the clamps. These cars would really benefit from an additional exhaust hanger right before the rear axle.
