1hd-t downpipe, where to get one stateside?

[Dusten]

I want to have a local shop build me a 3" system inside the frame rails on my hdj81. I was told by torfab to basically get a downpipe and have the system built.

Which leads me here. Who, or where can I get a 3" downpipe?

Great question @Dunsten! We are getting ready to get our 91 HDJ81's exhaust replaced and I have been wondering the exact same thing. The exhaust shop I went to for a quote said they'd probably be able to do a 3" system (factory routing), but they were not clear on the downpipe.

The Manta exhaust for a HDJ80 runs inside the chassis.

I also can't find a vendor that ships it here. I'd love to just buy a full kit and do it myself.

We can supply Manta systems and use them ourselves but heads-up that shipping a complete system will cost in the order of $600 AUD.

Drop me a PM if you'd like to discuss further.

Looking at mantas sit that puts an aluminum kit at least than 2k aud shipped. That's not bad.

Buy or cut a turbo flange and fabricate the whole thing.

Check out my sig for pics of what I did for my turbo build

I previously did essentially the and thing for my hdj81 (no pics)

Pardon our interruption...

I just bought a Legendex from Superior engineering for my HDJ81. Yeah, shipping was crazy, but it was also here in a week, which isn't bad.
I've built custom exhausts for my other cars, and spent in the $1500 range, and this was a little less, and I just bolted it on in a morning.

Just my $0.02.

I've spent double that. It wasn't cost putting me off. I was having issues finding exhaust that'll ship. This thread has found two

Weird flex, but OK. Hope you find what you're looking for!

The point is, cost isn't my concern. Availability is.

And my lightnings exhaust was a tick over 3k.

I did mine out of 3inch 304, turbo flange, flex joint, muffler, pipe and hangers for just under 350$. If 2k isn’t a big deal, bring that thing over and I’ll make it from the turbo flange all the way back .

Forgot about 3 SS v-band clamps and it’s all inside the frame rails, and purged.

Can you have it done in a day?

Downpipe takes the longest, but I can use mine to make a jig and get started on it while waiting on material to show up, but after that ,a day no problem .

 

[ZCissner]

I can make a few if people are interested, then they can just have a local shop build from there. I’ll cut a SS turbo flange this time. Just let me know

I'll shoot you a pm to get a realistic cost and such. I'm only an hour and a half drive away.
I ask about a day because it's my daily and if it's down for very long it raises cost due to time and inconvenience if that makes sense. A full kit I can install myself in a day vs having my rig down for fab work.
