Does anyone know the best (and Cheapest!) place to buy 2 into 1 collector pipes. I need a couple 2" into 2" and a 2" into 2.5". Also thinking of Camcoating the exhaust primaries, the pipes are 4 yrs old with slight pitting, what prep do you have to do to them? Anyone got experience of Camcoating?
Thanks

What's camcoating?

Ceramic coating? As spelled by a student. ;P

Ceramic coating, according to my Googling
