Where can I purchase a coupler for a stock '97 coupler to a 3.5 pipe? Seems every place I check just has round ones and ours is oval. Also what is the diameter of the oval throttle body? Thank you.
A 4" to 3" or 3.5" will not work. I tried just about every option under the sun when I was doing my intercooler piping. I eventually gave in and just ordered the one from Hellion. It cost me right at 68 bucks shipped. I found a bunch of places that would make them, but required that at least 100 pieces be ordered. Just spend the money and get the Hellion piece, or wait for the one the guy above is offering.
