    I was told by the guy at the local muffler shop that I had a cracked exhaust manifold under the heat riser so I've been looking around for a replacement. I found a guy that will give me/ sell me a brand new in the box set of Thorley TRI-Ys for a hundred bucks(inc. weld on adapter for O2 sensor) I checked and they are the right ones for my year/ engine but there are a couple of problems. The major problem is they dont include a connection for the air injection set up. I'm not subject to a sniffer test here but am unsure if I can just take off the injection system or will it mess with my ECM. The other problem is they are chrome and I am not a big fan of anything chrome. Any advice will mean alot. Oh, I have an 87 K5 350, 670 cfm TBI, Edelbrock(sp?) intake, stock exhaust. 208, 700r4, 4 inch lift

    yea, DO NOT BUY THEM!!! (instead give me the guys phone # and I'll buy them from him instead, happily! LOL)

    OK here is what you do, get the headers put in and disconnect all the air injection stuff. you can then leave the smog pump connected, but you can disconnect the belt so it doesn't turn the pump anymore. I just did this with some aftermarket headers on my other k5 (not the one I posted about that completely died in about everyway possible).

    Buy them. I just spent close to $400.00 for them. If you do not like the chrome, wrap them with header tape. But that finish will last a lot longer than the finish on the cheaper headers.

    I spent $350 for mine. I did not want the chrome either. But they blue fairly quick. They should be getting to the same shade as the Burb shortly. I was impressed with how well they fit, and how easy it was to reach plugs and bolts. Do not have any before/after performance info since I put them on when the new bullet whent it.

    Go through the mud and they turn brown anyway.

    Get them, they're the best headers money can buy. And ditch your smog pump along with all your other useless emissions controls except your PCV valve like I did.
