Also can dial up a bit hotter and straight line weld it. Just need to move faster on it. I dont pattern any welds these days when doing this type of work with wire feed. Hot flat welds and let it sizzle.

[@ST-cy6we]

That's good work.. I'd be happy with welds like that

[@eastwoodco]

Hope you enjoyed it!

[@fireblow44]

How'd it turn out? Does it sound good?

Just ordered my pipe cutter from Eastwood yesterday ......Im a do diy exhaust guy and this new cutting tool is goin to up my game so much ....cant wait to get it and try it out....Thanx Eastwood.

[@eastwoodco]

It is SUPER convenient - let us know how it goes!

[@rickmartin2154]

Nice you can now match the aluminized finish.

[@byronrichards3001]

Nice upload Eastwood, you guys' knowledge and experience is very much appreciated. Keep informing the people...

I don't pay alot for the exhaust parts, unlike the expensive pre-made Magnaflow direct fit exhaust system, with everything on it. I look at my existing exhaust layout, then get junk yard exhaust tubings, straights, elbows, flex pipe, flanges, hangers, resonator, muffler, etc. I got the larger sizes, instead of 1.75 inch, I got the 2.25 inch, then assemble it myself. Instead of paying $1000 canadian dollars before taxes, I got it done myself for drastically less dollars. I also get the mandrel bent elbows, magnaflow and borla mufflers, and nice chrome tips. The non mandrel bends are either crushed or wrinkled, while the mandrel bends are smoothly bent. I am going to use the Impala's dual exhaust axle back on the Uplander, with resonators in place where the Impala had its mufflers, since the van has its muffler, in the middle floor pan area, then add the Magnaflow muffler, and chrome tips at the end, coming up in the spring of 2025.

In case a slio fit is not available, is it ok to do an inner sleeve with a piece of tube with the outer diameter the same as the inner diameter of the exhaust pipe? Or will that create turbulence inside the pioe and be bad? Thanks to anyone who replies!

[@eastwoodco]

You're talking about essentially creating sleeve to keep the exhaust aligned and to build it easier. If you need to go this route for some reason you'll get the best results by keeping the exhaust tubing the same throughout, ex: 2.5" OD and then creating a sleeve with a pice of 2.5" ID that goes on the outside of the actual exhaust. This should keep the exhaust flowing as smoothly as possible as the exhaust itself will all be the same size.

Where is the High Temp Matte Black for exhaust paint located on your site?

[@eastwoodco]

Its under Hi-Temp Coating www.eastwood.com/satin-black-hi-temp-coating.html

[@gstaboy]

why only run the exhaust past the cab and not all the way back? Any advantages or just cost saving?

[@eastwoodco]

The truck is on air ride and lays on the ground so there's not much room to bring it back any further.

[@sleepercore7725]

That's one reason people do it. Some people like to have their builds have side exit exhaust

[@eastwoodco]

For this specific application you would need to cut a hole in the sheet metal for a side exhaust - again the frame and body lays on the ground.

[@davetaylor2449]

I wanted to see you fab over an axle, you know like in a typical installation

[@eastwoodco]

We're really focusing on the welding techniques here more than the design of the exhaust which will be unique to each vehicle.

[@paudiaz4660]

But why weld stainless pipes with carbon steel?

[@stephenhickman9502]

It seems in my mind that the slip fits would be the other way. Im guessing that the male end pointing towards the flow source is not a turbulence problem? It's not a back pressure problem. Just a guy whos never done it thinking out loud. 😆

[@eastwoodco]

The amount of difference is going to be negligible, so if that works better for your application we'd say go for it!

[@jonahseabarkrob6237]

The butt clamp is still for sale?

[@eastwoodco]

We carry this one Cody mentions from IC Engine Works: www.eastwood.com/ice-engine-works-1875ehseries-1-7-8-od-tube-tack-welding-clamp-4-pc-set-1875ehttwcs.html

[@markcnc]

muffler ? LOL Cat ? LOL Deleted 🤣the one thing NY has right on older verhicles

[@jdavidlangston78]

How is it DIY to use pre-bent pipes? Oh! Order an expensive kit and hope the right things arrive.

[@eastwoodco]

Ordering an exhaust tubing kit with pre bent piping means you only need a saw to cut down your exhaust.

[@theroyalcrownedtiger2946]

Its diy, since you still have to do the work yourself, order, receive, unpack, measure, cut, fit, weld, etc. instead of having a shop doing all of it for you.

[@CurboroughSprinter]

It’s still DIY in the same way that building your own house is DIY even though the wood comes pre-cut and not as trees. 😂

[@theroyalcrownedtiger2946]

I get my exhaust parts all from the junk yard for low prices, after looking at the current exhaust system, and make it myself, including magnaflow mufflers, tips, and so on. The junk has has it all, you do have to go there, cut off what you require, from different vehicles, then test fit for size, then put it all together. The premade magnaflow kit cost starts from around $1200 canadian dollars, before taxes, nah I am not paying that, I will make it myself at home. A ton of money has been saved, and am still getting the desired results in the end.

[@dylanb586]

Yeah lemme just whip out my 15k pipe bender and get some straight stock, that’s so much easier then spending almost the same on materials and using a cheap metal chop saw to cut the pre bent pieces to the angle you need. 😂🤡

[@MrGsxr10001]

just wanted to see how someone made the over the axle piece ? Not a bunch of useless crap......

[@eastwoodco]

These kits have 180 and 120 Degree Bends that would be used to go over the axle if you're running back that far.

[@WatanabeNoTsuna.]

No need to be rude. Its a very informative video.
