If you go to Summit Racing with some $$ (about $60) you can skip the cheese and get a hi-flow (higher than stock) cat.

Though I went to TPIS and got a Random Tech cat because I wanted assurance that it was very low restriction, so I paid the $250 price for brand name.

Yeah.. it is a PFP brand.. I had one on my 89 for about 4 years.. Seemed to work real well.. Especially for the price..

Rubbing alcohol is 70% isopropyl, and 30% water. Dry gas is 100% alcohol, but check the label. Some dry gas is methanol. Isopropyl is better. Do not use rubbing alcohol. You will be adding water to your fuel tank.
Okay. Back to the origional question. Where do I buy isopropyl or "dry gas"? And I am forewarned to check the label, to be sure it isn't methanol.
