Flowmaster 70?
Flowmaster 70? I have a 3 flowmaster 70 on a NA LS swapped 86 K10 and like the quite exhaust tone for daily driving.
Thinking about taming my exhaust down a bit on my 74 C10 which has a LS swap with a small Turbo. And using another 3 FM 70 is on the list.
Wondering if thats going to cause any problems due to back pressure?
The build is a mild sloppy 4.8 with a cam and a ON3 69/76 turbo. The exhaust is 3 and I have an exhaust dump when I want to let it breath.

As long as you have the cutout, you can run any muffler you want that gives you the sound level you want. If you measure the backpressure with cut out open and closed you can tell us how that Flowmaster works
