Has anyone here ever used a MagnaFlow / Flowmaster / Pypes system with an N25 bumper exhaust? If so, how much modification was needed for the tailpipes to line up? Pypes makes a system for '68-'72 442 & '70-'71 GTO which places the pipes slightly higher for the Valance/Bumper exit. Just wondering if this system could be used for the N25 exhaust without too much modification. Pypes told me no one has tried this that they know of so they can't accurately comment.
I had an exhaust shop modify my existing 3” tail pipes to work with my aftermarket tips. If you are using a completely stock system with 2” tail pipes and stock tips, then use a system from Gardner Exhaust and it will fit like stock with stock tail pipe brackets. Anything else requires some modifications. There are plenty of threads on N25 if you do a search. https://www.gardnerexhaust.com/ BTW, I use Magnaflow 14264 mufflers.
