Stock to Dual Exhaust Starter Routing

I searched quite a ways back and I didn't find what I'm needing help with. Im thinking of taking out my stock Y-pipe single exhaust and running true duals. The passenger side down pipe is shaped around the starter and has a pretty deep depression to clear the starter. Does anyone have pictures of how the routed their dual exhaust down pipe? Will I have to replicate the indention to clear the starter? This is for a 70 c10 with 350 and TH 350 trans and rams horns. I'm not going the high toque mini-starter route. I have no idea how to make this work or even how to direct my local muffler shop. Any suggestions or examples? I'm stuck.

Thanks!!

Pretty much down and back, then an angle at the bottom. I don't remember an indentation in my old exhaust system with the factory manifolds, but that had a 2" pipe.

Re: Stock to Dual Exhaust Starter Routing

I have the exact setup as you. Installing a mini starter will eliminate any interference with down pipe. After removing the original style starter I would never go back to that big heavy Delco type. Many advantages with high torque mini. Weight, cost and simplicity of instillation.....

Re: Stock to Dual Exhaust Starter Routing

I have the same 350/350 setup on a 72 LWB C10 and took mine to a muffler shop and told them I wanted true duals from the rams horns back. I have a normal starter and they did what I asked and I had an H pipe added as well. Sorry I do not have a hoist or I'd post pics for you.

Thanks!

Re: Stock to Dual Exhaust Starter Routing

Here is how I had the exhaust exit the truck.I wanted the pipes a little further back to look like the pipes on the black truck but because of the factory auxiliary spring set up that's as far as they could go. The link is what I use for mufflers and it gave me the sound I wanted. We can't post videos on here but if you want to hear mine running PM me your personal email address and i'll send you a video of the truck running. The mufflers are sideways under the truck. In case the link just takes you to the site i used part number 17747 on my truck.

Talking Re: Stock to Dual Exhaust Starter Routing

Just take it to a good muffler shop and they will take care of it for you. The only thing is next time you have to take that big ass starter out you may have to undo the exhaust to get it off.
This is why the mini starter is nice.

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

I'm have to admit you are right about the starter. The exhaust shop that i'm taking it to recommended a "slip-joint" just past the downpipes for just that reason.

One last question, should i retain the factory heat riser? I'm in the sunny south so cold starts are not an issue. Come think of it I'm not sure the one I have even works.

Thanks again.

I wouldn't worry with it unless your going for a all original look. Which I doubt since your going dual's. I've never had a problem with either of mine.
I have done the LS swap in my 71 with headers. I hope I never have to mess with a starter!

Re: Stock to Dual Exhaust Starter Routing

I have a regular starter and an NV3500 5 speed. I can remove the starter without removing the exhaust. I only remove the hydraulic slave cylinder below the starter.

Re: Stock to Dual Exhaust Starter Routing

Now that i think of it I had the exhaust installed in 2015 and last year had the starter replaced and nothing was said about having the exhaust interfere with the starter R & R..

Re: Stock to Dual Exhaust Starter Routing

I've been following this waiting to see if anybody had anything to say about the Hooker dual exhaust kit (16621HKR). The down pipes look the same on both sides. The reviews on Summit Racing are mixed. One person said they hang too low, but others say they fit perfect. I'd like to try it because it has mandrel bends and a decent price. I'd really like to see some pictures of it installed.

Re: Stock to Dual Exhaust Starter Routing

The shop should be able to manage any issues you have with interference and with future ease of replacement of the starter or other parts under there.

Let them decide and then have them show you before they weld it up.

Talked to the shop and taking it on Monday. This is definitely the right place to go. his first question was how to I intended to use the truck and cautioned against going too big with duals for a bone-stock 350 used as a daily driver. not sure a lot of shops would recommend sticking with a single exhaust when they have the opportunity to sell a dual setup. He also builds the system so you can tryout different mufflers to get the sound you want before before you leave. I see how it goes.
