1986.5 Supra, Just bought this afternoon.

That's what I was thinking, the exhaust does sound pretty shady. The lady that sold it to me said something on it rattled loose and now it sounds like a cheap fart can... I swear, the drive home was almost embarassing. A Crossfire jumped me on the freeway and I was helpless, I had to floor the damn thing just to keep up with traffic.

Stupid work. I hate work. I wanna go home, why doesn't my boss understand that I have to go work on my car??

[edit]
It probably is the exhaust, too. Especially if it has an old cat now that I think about it. The lady was really sketchy about making sure I understood that I was responsible for smog & registration. Probably failed a couple smog tests with a crappy cat. Oh well, I will be putting in all new 3" exhaust/headers/cat in a couple weeks, so I hope that will get rid of it. In the meantime I'll get the tune up done and run a test pipe to see if I get the RPMs back.... After I get my new radiator. :P
