there not enough air around the exhaust to spread out the smoke (I'm sure there's a better way to say that).
I used to have a fair bit of black smoke when i booted it under load but since decatting and sticking the straight through on it seems to have all but dissipated under load and runs a lot cleaner- a lot louder but a lot cleanerSo I haven't broken me car yet? Lol
That's good to hear!
Just a thought after Xmas I want to get a straight through decat exhaust, will that make smoking less or more apparent, or no difference?
