Made an exhaust.
4 inch Dump pipe
4 inch exhaust straight pipe
My car has been super quiete with a 3 inch dump pipe and twin 2.5 inch exhaust with X pipe muffler.
It is not a daily driver so im now going loud and hopefully fast.
I always liked quite and fast cars but I now need less back pressure for spooling a big turbo. I had a 7675 T4 open, Journal bearing .96ar it made 20 psi around 6000rpm which is ok for drag racing with a powerglide as it stays in high RPM the whole run but not fun on the street on mid range.
It was a bit laggy so I put the 6266 gen2 .84 on for roll racing but its not fast enough to hang with the fast cars in my area.
I just bought a 7675 T4 divided bb sportsman so I will need all the 4 inch exhaust to help.
Video of 4 inch dump and exhaust (This is mocked up onto a 6466 gen 2 1.0ar but Ill make the dump fit the new 7675)
