I read a recent post about mufflers and I just wanted to ask if anyone has had luck with tsudo? I have the sp2 on my cavalier 2.25 with the factory resonator and cat converter and it is really deep!! I really love it I have had magnaflow and borla and this is by far the best in my opinion for a n/a ecotec. It does have a little cackle at about 4k
I had a Tsudo on my 96" Z and loved it. It was a tad loud for some people but I liked it. I had my factory cat and resonator in place with the muffler as well.
