I was on the corral talking about exhaust combos, and the topic of Longtubes got brought up. Two people with longtubes said it made their exhausts quieter and more mellow at idle and cruising....WTF? One of my friends has a '96 Impala SS with a flowmaster catback, and when he added longtubes, it made a NOTICEABLE difference. It was not only louder at idle and when revved, but it had more SNARE to it...it sounded meaner and more p!ssed off.
It doesn't make sense how a long tubular header that flows gases much more efficiently and faster would be QUIETER than the choking/restrictive stock manifolds. I have a UPR o/r X and bassani catback, and while it has a great tone and is loud, I want it noticeably louder, so I was going to get some Longtubes for xmas, but am reconsidering after hearing this, although it doesn't make sense to me.
I was hoping to gain several db's and add more bark to my exhaust with some LT's, and logically it seems like they would. Someone please help me out here.
