replacement exhasut insted for donuts

[Jona$]

Did the test of putting a rag in the exhaust but the sled keeps on running.
couldnt even smell or see any at donuts, perhaps y-pipe.

My question is isnt there any replacement for all of this, i believe mcxpress has some since i have the 290kit.

I had the thistledoo donuts last year but they are pretty weared down, and the ends of exhaust etc dont clam tight i believe.

did a checkup today, all 4 flex-joints were good, can salvage the copperdonuts with some copper silicone.

but the titanium y-pipes were cracked both of them , so ordered the stainless from Erik at mcxpress
