Exhaust Tips

I have a 1968 GTS with a 440 and a full 2 1/2" dual exhaust system. I had the same issue as you and my solution was to install Flowmaster Exhaust Tips 15385. They look similar to the square slant cut stock tips and come with an excellent clamping system. The only small fault is that they have the Flowmaster logo on them. Check them out on Summit's or Jegs website. I am very happy with the price and the near factory look!
