But I have installed quite a few sets of patriot side pipes and have them on my Astro and 85 b150, they definitely improve the look.


When in doubt..get the sawzall out..

I have patriot side pipes with headman headers. I love em. Wish they were a little louder though.

FWIW, when I put patriots on my Chevy, I bought the 80” because I had a lwb van. Fit perfectly but we’re quieter than when I brought it in. It’s essentially a super long muffler so I just took that out, had the shop weld in a section of straight pipe and then a short 12” glass pack near the end of each side. These were with hooker headers and boy did it wake the sound right up.

I think the STOCK side exhaust for 67 came off a rams horn manifold and then the pipe made a bend toward the rocker panel and then was basically a chambered pipe type muffler (like the GMMG muffler) that ran along the side with a cover. However, I know there are headers available that have the collector pushed all the way out to run parallel with the rockers and a side exhaust can bolt directly to those collectors. Are these headers what you are wanting to run? if so, a 3rd gen chevy van is about 10" wider than the vette so I would assume you would have to cut them and weld extensions into each pipe to move that collector outboard to match up with the van rocker. I would find a C2 vette and measure the width at the rockers and then measure the width of your van to get an idea of the difference. also, I know that people use 2nd Gen F body headers on vans a bit, but I don't think I have ever heard of Vette headers being used, so there may be some other clearance issues there, too.

I have a set of old Hooker super comp headers for my Dodge they are for a truck so they don't fit. I want to cut them for that very purpose, a true set of 4 into 1 side pipes sound awesome.
