oh- i would like to add about my BBK's: for the price i can't really complain, but i was very unimpressed with the weld quality, and the chrome finish. since i have a couple years welding experience, it was not a big deal for me to fix, but the quality was still sub-par. Every one of welds had a lot of overlap that i had to grind to make the transition smooth. there was a TON of spatter, and even a couple 1" pieces of mig wire inside. Two of the welds had holes that i could see right through. i would be so pissed if i hadn't noticed them until after install. and the outside of the pipes had many rough tool markings on them (from the bending i presume) which were just chromed over and did not look good. my car is definately no show car, but i had figured they would be better quality than what i recieved. maybe i just got a bad set, but whatever. if they hadn't come from the states ( i'm in canada) and were bought locally, i probably would have returned them. but they did fit nice i guess!
