i loved the totl exhaust that i put on my ls1, what i loved even more were the mullets that were dumbfounded that i replaced (fake) dual exhaust with more efficeint two pipes on the left side.
plus i think i paid 300 bucks for it from slp. It was on sale. I was very impressed with the performance and as for quality ....... I figured it was american, so i didnt expect much.
