Exhuast Mockup

Since I can't tow or drive my truck to the muffler shop I was hoping to make some type of a mockup to bring to them, showing them the bends. Should only be 2 bends, but measurements alone would be kind of iffy. Anyone have any good recommendations? I'm hoping to run down from the manifold, back half way, then about 45 turn to exit in front of the wheel well

I'm curious why it can't be driven or towed to an exhaust shop. What make/model is it, someone might already make a complete setup for it, and the kit will have mandrel bends with most shops don't do.

It doesn't have an exhaust on it, so can't be driven there. I don't have a vehicle to tow it there with. These places have mandrel bending equipment. It's a 41 Chevy Pickup on a 92 Nissan Frame w/ a 92 Nissan Engine. Guarantee they dont' make an exhaust that will fit and also exit out the side. Specially for $80 doin custom is a butt, but fun

I'f it were me I would drive it. I would imagine you could drive it to the shop without getting pulled over, and if you did, politely explain your situation I'm sure you would be let off, and if not it's only a $25 noise violation. Certainly would be worth sparing the aggravation of trying to explain to a shop what you want without a vehicle and then installing it yourself hoping everything fits.

I have heard guys talk about mocking up exhaust using flexible exhaust tubing and injecting insulation foam into it once it is in the right shape to hold it in position. Still, I would deliver the vehicle there for them to work on it.

Just curious but what's the name of the shop? Most shops don't have the capability to perform mandrel bends... the equipment is very pricey. Make sure you see some of their finished product.

I'll have to check. The first place is a Meineke franchise, the other is a local shop that's pretty big. Why does it really matter? This isn't a high performance vehicle by any standards. And it'll just be about a 30 degree bend and a 45 degree bend, just curious

If it's not a performance application it won't matter if it's a mandrel bend or not. I've had exhaust systems bent by exhaust shops that worked fine and they weren't mandrel. I have also driven my car to the shop with open headers...350 sbc at that time. Didn't see any cops so guess I got lucky.

Finally came up with a good solution. Going to use PVC pipe of the same or similar dimensions, then use a propane torch to make it flexible.

good idea, the plastic fumes will only kill two or three people behind you, so thats fine. Dude, don't worry about driving it, just go slow and get it to the shop. If you get pulled over tell the cop that the exhaust got screwd up and you had to take it off because it was dragging on the ground and didn't want it to be a road hazard. Tell him you're on the way to the exhaust shop right now, even make an appointment so you can back yourself up.

I must really be retarded. When I read his thread, I thought he was going to do a mock-up. You know... and then carry the mock-up to the muffler shop, have them bend the exhaust, carry it home and then install it on the car. I should have known he was going to do his exhaust using pvc so he could then drive it to the muffler shop. What a great idea. He'll most likely need to keep his speed up to get adequate cooling on the pvc.

I don't know what I was thinking!
