I am asking this question because I am going to straight pipe my supra and was wondering if anybody knew the answer to my question.

Now before you ask, yes I did search ask.com, google, msn, and yahoo and found nothing.

So please help me with this.
 
2 inch. Clayton bought a stock exhaust system for the Supra and it turned out 2". I think I had a 2.5", but my memory is fuzzy. Airjockie should remember for sure.
 
That's something that I never really measured. 14" sounds about right. I feel that the engine breathed better with the 2.5" exhaust that I had on it, but the stock pipe that Clayton put on it sounded very sophisticated and soothing. (It wasn't belieing it's high-end nature with a ricey sound). It was quiet, and smoother.
