Trying to ID the kind of exhaust on my '96 Z28 (bought used). The muffler is odd. No markings (that I can find) - and it has squared off sides - like a big rectangular shape - as opposed to the conventional oval. Anybody know who makes a camaro muffler with this shape? ...or how to find out what type of exhaust it is?

 

Possibly a SpinTech?

hmm... maybe. I checked their website. I will take some measurements and compare it to what they show on their site for overall size. The pics of mufflers they show all have the spintech name on them - but that may be just for presentation on the website.
