My '82 has these great 2 1/2" (OD) slanted exhaust tips that I'm used to, they look great, I think they're perfect for the car. Along comes my '83 with those pathetic little 1 3/4" (OD) round pipes. Ugh! Went looking for tips on the net after first checking out JC Whitney. Some 40 net pages later still couldn't find what I was looking for. Thanks to Bruce Benson I took another look at JC Whitney. They have these great looking highly polished 2 1/2" OD SS slanted tips for $13.95 each. Only Problem, ID is about 2". OK, I can Mickey mouse something. (Part # 47TS2884P). Installed them today, look pretty good for a first effort but I'm not quite happy with them. What I did was make 4 slots in the back with a hack saw, then pounded in two opposite sides slightly so that the other two sides would sort of overlap and clamp on the small pipe. Also from JC Whitney I ordered 2-SS 2" clamps (83TS0713Y). Pounded the ends down to where the clamps would fit and clamped them in place. Almost happy with them but think I'll take them off again and use some exhaust pipe reducers and larger clamps so that there isn't such a difference between ID and OD. I heartily recommend these tips but not necessarily my installation methods. The job looks pretty good though, if I do make it better I'll let you in on it.
