I run custom 3" front pipe to catco stainless barrel cat 3.5" to the resinator 4" from there to the cannon its a hks exhaust .I picked up 12rwkw when I did thisover my old 3" exhaust and that was a trial

Cheers Peter

I went from a 3.5" mild steel, to a 3" stainless and lost 4kw at top end - gained 5-6kw from 2000-6000rpm. R32GR 237rwkw. Think it depends on your power level as well as cats/mufflers/diameter.

the reason you gained mid power was because the air could syphon a bit better with the smaller piping, but at top end you had obviosly maxed out that size piping.

or it could've been due to different whether conditions, etc etc etc.

A few ppl have mentioned it but it bares repeating..the most restrictive thing in your system...is the cat, provided your system wasnt manufactured by a complete loser. I changed to a "spec R" cat ;) on a 3" mild steel system with x-force dumps and genie front and cat back. I picked up 20 HP at the wheels on my 32R. Next time I'll go a better quality hi flo cat and go bigger dia dumps and front.

They were back to back runs so that eliminates several variables, either way, power level only slightly differnt - barely noticable, but the differnce in noise was considerable.

    • 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.
