Been trying to find a flowmaster cat back system that uses the 40 series mufflers and not the american thunder, the force II's or the super 44's. I want that old school 40 series sound I had with my older muscle cars.

MU71L4710N

for what year....?

summitracing.com sells the tail pipes and flow tubes (intermediate pipe) separately for the new edge mustangs i can tell you that much. so you could buy those, and 2 mufflers and have your own kit with whatever mufflers you want. there may be some minor trimming or modification that needs to be done but any exhaust shop should be able to do that.

or you can buy an american thunder catback, and buy 40 series flows and just swap em out, then resell the 44's to recoup most of the cost.

+1 on summit racing. I bought my set up from there..

I guess it would help to let you know it is for a 91 GT. Guess I should fill out my sig.

there both flowmaster tailpipes for 140$

there are some flowtubes by flowmaster (connects H/X pipe to muffler) for 80 bucks.


and you will need 2x of your 40 series flows. again, there may be some minor trimming, welding, etc... that an exhaust shop will definately be able to do for you because of different muffler sizes this may or may not bolt right up without a little cutting, but shouldnt be anything serious. i'm sure you can email flowmaster with the part numbers and see what they say also.

That's perfect man, thanks. I work as a welder/fab so not much issue with the trim and weld part of it. I wasn't thinking to look for pieces and parts and build to fit.
