I'm sure someone has offered already but just in case... i have stock header and downpipe for a 93 vtec. let me know if you want to buy it. Or, since you only need it for smog, i'm willing to trust you with its safe return(see prelude owner code of conduct!

if you want to drive down to the valley (calabasas) and pick it up. Either drive it back to me or send it back. whichever is best. I'll ship both peices to you for 120. I also had smog this year, i had to buy a new cat to smog. I had the shop cut off the stock honda cat flange and weld it to the new cat so i could bolt on my exhaust. Unfortunately my car was totalled exactly one week later. so i've got a new cat if you need it too. all 3 parts shipped for 170. Or get back to me about loaning to you.
