Hello I have a 78 futura and prev owner has flowmasters with dumps before the axle. I hate them cause it sounds like a old grain truck at cruise speed ans plus the fumes is dumb.
Anyways american muscle has some sr performance 2.5 axle back pipes for 159usd. I can make some but wont be stainless for about 85 bucks.
Question will the mushrat pipes xome close to fitting or will not come close? I have a 8.8 axle if that makes a difference I doubt it as they are the same but this has quad shock brackets on the diff.
Would like to do subframes and tail pipes this winter.
Maybe a bigger carb and k and n eci. Depending on a vac test under load testing. Then on to my 68 mustang 289 as the Futura has no more mods left that I am interested in.
Anyone with any experience in the exhuast topic is appreciated.
