4 in to one header
« on: February 08, 2009, 03:27:43 PM »
The 4 head pipes appear to be jamb fit into the collector, with only about 3/8" to 1/2" engagement. Is this normal? I am going to have the header ceramic coated. Anything I should know? I've gotten the 5 pcs apart. Need to bang out a couple of dents.Also I need flanges to replace the ugly cast finned originals. Thanks for any info.

We probably need more info, but I'm guessing it's a factory 4-1 on a 400 or 550??

I'm not sure how far they are supose to go in, but I'm sure someone on here does.

Sorry, it's an aftermarket exhaust. Don't know what make. 77CB750 K7
