1970 k10 4x4 exhaust system - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Pretty difficult to find a kit. Anyone know where i can buy a kit (the transfer case is in the way- pretty rare truck in 1970 from what I gather...)
Thanks,
Scott

oh- standard 2.25 inch (i believe) rams horn exhaust is on the 350 I put in it.

Did the 1970 have a Rockwell or an NP205? Not sure how much of a difference there is between the two.

I used an LMC kit on my 72 K10, but also scabbed in a few 45 degree elbows from AutoZone to go under the t-case, temporary fix that has been in place for about 5 years now. One day I'll run my pass side pipe over the t-case.

Been collecting photos of this very thing in hopes of fixing mine one day...

I have bought 2 Y- pipes from these guys. Both for 72 K/20’s.

Hi Joe,

Would you have a part number for the K20 Y-pipe handy?

They don’t have a part number. They are made to order. I just got one about a month ago. It’s about a 4 week lead time. They are very easy to deal with on the phone. Mine was $240.00 with shipping.

I've always taken mine to a an exhaust shop. It's usually done in a few hours.
