I'm thinking about custom exhaust.

Actual setup: R34 dump pipe ( 58mm), RS*R downpipe (2x70mm to 85mm), ultra quiet resonator (76mm), 76mm straight muffler and finally a varex 76mm exhaust.

I plan to go with : Tomei 76mm dump pipe, custom downpipe 2x 76mm extra long with a 76mm resonator welded then it would merge into a 100mm muffler and finally another muffler at the end.

However, do you think its possible to fit this under the R32 GTR? Anyone have done it before?

I've got twin 3 inch for the purposes of a 30/26 but haven't run it yet.

Piggaz have you got any piccies of yours? Do you run cats then just one set of muffs per pipe or resonators as well?

Piggaz has a Racepace. So dual CATS, 2 Mufflers on each pipe... And as he said, it is very very tight in some places as a result.

And hence I'm gonna say - Twin 3" just weighs & costs FAR too much for what you get out of it. Easier to just go with a single 4" which is good for 400rwkw+ anyway. Is lighter, cheaper and you can get two massive mufflers for the same noise reduction. (looking at a GB of 4" exhausts in a few months :))

If you are dead set on doing it you don't need the two resonators as you come off the front pipes. Two _asbigasyoucan_ mufflers on each pipe will be very adequate. It would be a SUPER tight fit on a R32 that's for sure.

thanks guys for the input! didn't know they were 72mm.

why I wanted to run twin 3 inch was in order to fit the 3'inch ultra-quiet resonator ( they do a great job, I have one right now) and then it could merge into a 4inch exhaust.

I still need to fin a dump pipe bigger than the r34 oem right now.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
