I have a series 1 Rb25 swapped into an s13 sitting on mckinney motorsports mounts. I changed my exhaust manifold today to an aftermarket one and it messed up my clearance between my dump pipe and steering shaft. I found this one below on ebay and i was wondering if this would solve my problem, or if anyone knows of somewhere else i could get one could you please let me know. Thanks

No one has used an aftermarket dump pipe in an s13?

fitment issues on bolt holes, and thats larger than the oem dump so its safe to assume it wont fit

The clearance issues with those elbows is from the wastegate tube hitting the steering column. A member on here, CA18magic, tried installing one on his 20 with tophat mounts and said it wouldn't fit. You can try, but I don't think it would work. If you have the cash, Part Shop Max has a complete elbow/downpipe that addresses that issue.

I guess there's a couple of things you could do: 1. ditch aftermarket manifold, and go back to stock manifold. 2. Try to file down all the mounting points a millimeter or 2. Try to hack up an ebay elbow. 4. Make your own elbow. 5. Buy the PSM unit and cross your fingers.

I've seen some aftermarket elbows 'hammer fitted'. Stock elbows are simply grinded away since the castings are so thick.
