Sorry if this has been covered. But can I use an SR20 downpipe with my RB20 outlet in my s13? If the outlet is differnt can I use a SR20 outlet + SR20 downpipe?

if you already have a SR downpipe then just cut the flange off and reposition it. its what im doing since i went from a SR to RB. im cutting my blitz downpipe and cocking the flange

I did the same, bought a nice SR down pipe and cut and rotated the top where it bolts to the turbo, I also took a little bit out of it so it wouldn't hang low under my frame.

i'm working on developing an o2 turbo-back section that will uses any sr20det downpipe. this will help you guys that have trouble getting a downpipe and also help with clearing the steering shaft. stay tune.

Hey Guys,

Sorry to necro post but I felt this thread could help answer my question as well.

Basically I have a SR set up but with an RB downpipe. Is it possible to rig the RB downpipe with the SR? If so what needs to be done?

Thanks

I used one. I had to cut the pipes at the flange at an angle so it pointed more towards the passenger side of the vehicle. Then had it tig'd back together. Then i put a downpipe together myself. I'm getting better at mig welding. Get the one from ssautocrap. It's a decent piece and it's cheaper than they go for on ebay too. I'll try to get some pics.

ok but I want something to buy where I don't have to do any of that extra work.. I want something that will bolt right on and clear. lol

anything out there like that?

I did a lot of searching and couldn't find anything. AM performance made one but i couldn't find one anywhere. Elbow was only $50 and $45 to get it tig'd back together. It wasn't much work and probably cheaper than anything else you will find. Good luck though.
