I Have a RSR downpipe currently bolted to the factory turbo/o2 on my 03 GSR. Iv noticed it has multiple clearance issues a major one being the factory sway-bar. Its in pretty bad shape from NYC roads. I want to replace the downpipe completly with one that has better fitment. Is there any downpipes that would be a direct swap to the RSR or would I also need to purchase a seperate midpipe for a diffrent setup? Additionaly I wouldnt mind swapping the o2 housing with a nvidia or somthing provided it will not cause boost creep.

 

Anyone? Search hasn't helped.

 

Alright made some calls, well so much for answering my own question. The majority of exhausts such as AMS and buscher require a separate test pipe. The AMS won't fit with my hks catback. It looks like I'll just pickup a buscher and test pipe
