I want to use a 86+ cat back on my 85 with the factory y-pipe. Are the flow tubes on the 86 kit oriented the same as the 85 pipe? Curious if I can cut the flow tubes to length, the 85 has two different sizes mufflers.
This would only work on your set up with doing a dual exhaust conversion. You may be able to have an exhaust shop modify this system to make it work, but modifying these will void any and all warranty's.
