dual exhaust for our trucks - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently bought a dual exhaust kit for my 75 stepper from Dynomax. I paid 115.00 They have various kits for headers non headers 4x4 or 2wd. Thr reason i am putting this in is I got the 89007 kit for a 2wd 73-82 truck. When I put on the pipes one side went in great, the other side had a header pipe miss marked so I called dynomax and they are next day airing me the correct pipe. Note: All the kits i have seen from them are 2 1/4 inch pipes. I know some people have been looking for dual pipe kits.

I used their kit on my 86 4x4. Only problem I had was the flange to the manifold was too big...

I used their kit on my 79 4x4. I was very happy with it, went togther easy, fit well, and included high quality hangers etc. I even stuck a set of mini-cats in it. Nice kit.

What did you get with the $115 kit?

If the link doesnt work goto Summitracing.com and type WLK-89007 in the search box.

You still need mufflers and catalytic convertors if you need them.

Forgot to add this does any one have pictures of the system installed? Or a better view of where the header collectors start at on the system? Looks like flexpipe and I don't think that would last very long most I have seen rust real fast and leak.
