I bought a set of original 40 series flows off my friend with flowtubes, they came off of a supercharged 85 GT...my question is will the flowmaster tails still slip into them like a reg flowmaster catback? the mufflers are 2.5" i would have too cut the rest of the old piping off them (it's less than an inch) i am getting flowmaster tips off someone on another site the tips are from a 94 cobra. I will also be selling my mac catback with 2.5" chrome tips and also have a set of 3" tips that i will be selling separately. any input would be great, also does anyone have a pic of thier install with the tips? thanks guy's
