How can I get a cheap but effective downpipe? I have a stock turbo. How about the rest of the exhaust? thx in advance.

Many stores will allow you to stack a coupon on top of a sale price. You can easily get one for 250 or less out the door. If you're not addicted to using it by the time you're finished, sell it on CL.
Cut mild steel bends on radius, make sure they fit up perfectly (easy task w/band saw) and tack them together with the welder. Take it to someone with a TIG to finish. Paint with exhaust paint if you're in a rust area.

04-12-2015, 12:14 PM #4serious question: where do you guys buy 3-4 inch exhaust metal cheaply?
'82 300D -3" straight pipe, ALDA deleted, 3in1 glowshift gauge, HX30, egr-less manifold, A/W intercooler
'14 Ram 6.7l cummins -G56 handshaker, wishing it was deleted
Honestly, it would probably be cheaper to go to your local metal provider and buy it. But I won't be aluminumized or anything fancy

04-12-2015, 11:23 PM #7Holy crap I searched for 3.5 inch/4.0 inch under the exhaust section at Summit Racing and the cheapest selections started at $250 for some piping
Stainless will be expensive, mild steel not so much.
No exhaust manufacturers nearby? I'd look for an exhaust shop localy and try to pick up some exhaust pipe there.

Buy the straight sections from your local steel shop for almost nothing, fancy madrel bent stuff will cost quite a bit, if you can cut angles ect you can do it that way. Just won't be as smooth as it could

wut? You're doing it wrong. They have 3.5 mild bends in the $40 range. A whole 3.5" mild steel exhaust build might end up using $250 in tubing and bends but that's not what I call expensive. Mandrel bent exhaust systems have never been "cheap" when compared to compression bend garbage.

Do I need to go bigger than 3 inch? BTW I don't think I'll be buying a band saw and a welder for a one time job. That'll be close to $500 - more than what I'd want to spend for one time use tools. Just sayin'.

04-13-2015, 09:57 AM #15Nah you don't need bigger than 3 inch. I can't imagine an exhaust shop would be horribly expensive if you purchased the necessary bends and had them weld/clamp it together with hangers and what not.

Butt welding stainless will need an argon back purge of the pipe or it won't last all that long. Mild is easier and tougher but has the rust thing.
Good fit of the pipes is important for good butt welds. With a bandsaw, my fitup is good enough for fusion welds (no filler metal) and I'm able to get my cuts on-radius the first try.
A nice cut and weld exhaust requires commitment to quality and detail that is labor and talent intensive.
