had another quesiton. I really need a new exhaust now for my stock 1600, but I also plan on upgrading to a 2100 or so engine in the next year or two. How much would it hurt the performance of the stock 1600 to get the 1 5/8" sidewidner now so I don't have to replace it in a year?
73speedbuggy: If you go to 1 5/8" for a 1600 with stock heads you will tend to loose low end torque. That might be acceptable for a year if you drive mostly on the street.
