I've been Pro Flowmaster for a while and noticing that you can get systems for 66% of the price of the Corsa Sport is definitely an attractive offer...but this past weekend I was at my dealer gettin my oilchange/wash and this guy has just finished putting Corsa Sports on his 2004 Z71 Silverado..so of course I had to ask'em to crank it up, which he obliged with a grin. I'm sorry..but there is NO comparison at all. That corsa is the sweetest sounding thing I have ever heard. He was stock exhaust/headers so nothing but corsa comin out the back.
When I get the money up Corsa Sport will be on my truck.
