A few months ago we bought a second-hand 3" dump pipe to replace the stock one in our R33 GTST. We looked under the car at the old one, then looked at the one we were buying, and thought they were the same.

The other day we removed the stock one, and realised that the new one was about 6" longer. As well as this, the flange that the cat bolts to is oriented different - ie rotated on the pipe so the holes don't line up.

Anyone know what this pipe might be out of? It is a commercially made one, with a brand name on it (which I can't remember - pipe is not here).

The turbo end mates up fine, and the pipe runs in the right place. The welded on mounting bracket at the cat end fits to the car's mounting point, but obviously the cat doesn't fit.

Any ideas on the best way to make it fit, without spending a small fortune at an exhaust shop?

Um.....define "small fortune". What are you expecting us to tell you? That you can whack it with a hammer and it will fit? I think it is pretty clear that if you want to connect it to your existing cat then you are going to have to cut the flange off, shorten the pipe and weld it back together so it mates with the cat. If there is some left-right offset or angle difference that means you can't make it connect, then you are better off removing the cat from the rear part of the exhaust and getting the mid pipe altered to suit.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
