Ive been trying to decide what downpipe and turbo elbow setup to go with.

I was either going to go with a Tomei elbow and HKS downpipe however i started getting concerned that i may not have adequate ground clearance, being that i daily drive my drifting device im going to have to worry a little more than i thought about scraping it and breaking stuff. I'm not sure how much lower it hangs than the frame rail but i would like to know so if youve got pics and a few words of your setup that would be mighty nice.

I really want to avoid scraping and breaking turbo/exhaust studs. I dont know how low a regular 3" Downpipe hangs below the frame rails, if its not much i should be fine.

I was thinking about going with the PBM Max flex cobra downpipe, it seems to have swell fitment and ground clearance but i'd really like to replace the downpipe piece if it ever gets scraped.

So please help me with my decision on which to go with by posting pics and maybe a review of your setup.

I bought this off of someone a few years ago and it gets great clearance.



I've recently seen them pop up on ebay

Ahh yes i have seen that one before.

I would suspect wonderful clearance from that, i have also seen the moonface ovular chamber style downpipe.

I'm curious to get a few pictures of how low a regular downpipe actually sits below the frame rails. I have seen the PBM one now i just need some regular ones for comparison.

These are the only pics I got.Stock t25, stock elbow, ebay downpipe

The whole exhuast isn't hooked up so the back is probably hanging down a little more then it usually would. I never had any problems hitting the downpipe and my car is all the way down on megan track coils(not in these pics), but the cat scraped on everything

Go with MAX.

Not my pics, but some I found of the PBM cobra installed. Shouldnt ever have to replace anything on it. For the price of the PBM cobra compared to a tomei/greddy/whatever o2 housing and downpipe youll pay more than the cobra and get less clearance.

Yeah ive seen all those pics of that one. It is nice for sure and the clearance is great however i still like the idea of a two piece design

Have fun replacing studs and gaskets with the 2 piece. None of them have a proper flex joint with ground clearance. But it looks like your set on a 2 piece, so why make the thread if your mind is already set?

I'm trying to see how low two piece ones actually hang since i havent seen any pictures out there. This thread is strictly comparison and to see how others go about their lives with their elbow/downpipe setup.

The PBM piece is amazing definitely, my mind is not set that is why this thread exists.

I know none of the two piece ones have a proper flex section but given enough ground clearance they may not need it, I havent scraped my exhaust system before but it was 2.5" and parallel with the frame rails im just hoping that can be achieved again with 3"

One thing about the PBM pipe which i cant use is the transmission mount bracket. I run a peak performance transmission mount which does not have the stock bracket attachment so i am worried that the PBM pipe would sag in that spot making the clearance worse than a two piece setup.

I too am interested in getting the PBM cobra however I also have an aftermarket transmission mount (Megan). I would like to know if the pipe stays parallel with the frame even without it bolted to the mount. Thanks

I'd love to post pics, but I'm quite a bit aways from home right now. I'll try to get someone to take pics then I'll post them up.

You should ALWAYS run a flex section on a turbo car, moreso when you have an aftermarket manifold. Things like to crack with no flex section. Either way if you run the trans hanger or not the PBM will have a lot more clearance than anything else. Also helps to hose clamp your rubber hangers up. That wil pull the exhaust up a good bit.

Yes that is true i believe the same thing about running a flex section if there is ANY chance that you may bottom. I have heard of the hose clamping the hangers also however i run polyurethane hangers so i think those do the trick already.

I run a Megan turbo elbow, Greddy DP, stock exhaust mani, stock engine/trans mounts, and stock T25. My DP sits about 3/4"-1" below the frame rail, same clearance when I ran the stock turbo elbow. I've got some scrapes and such on the DP (my car is lowered a bit over 2" as well), nothing major though. If I were going to slam the car, I would get a DP that is designed to sit flush with the framerail. Flex sections are good for SS manifolds too.

Since im going to be getting the Tomei manifold later down the road, i have decided i will go with the PBM Cobra DP because of its amazing clearance as well as its flexibility. My frame rails are 2.5-3 inches from the ground so anything lower than that will be causing me problems pulling in and out of driveways.

Now i just have to figure out whether i should buy the PBM Cobra with the diversion plate or the one without it.

Yeah, my frame rails are still ~4 1/4" from the ground, so you'd definitely scrape with my setup. I'd go w/the diverter plate is the cost isn't that much of a difference.
