Cat back exhaust differences series 1.5 vs 2.0

[LateApex72]

Just a heads up, I'm in the USA.

 

I recently purchased a 1997 RS4V that I absolutely love. I've started to hunt for exhaust options as I'd like to hear that inline 6 sing a bit and I'm having a tough time finding options for my 1.5 but there seems to be a much better selection for the 2.0. Does anyone know what fitment differences the later cat backs have vs the earlier models? I can see the rear bumper cutout is smaller on mine but I can modify that.

Thanks in advance!

I don't know (mine is custom) but I would expect all C34 Stagea to be the same from catback. Potentially front and rear pipe different between S1 and S2 with different motor but all the rest of the chassis stayed the same

Get some Vibrant mufflers and custom make whatever to suit, the OTS stuff is never good IMHO, if you're keen import some SP Mufflers from Australia.

They are superb, they used be known as SMB Muffler however was taken over by SP Muffler (same design, tooling, etc. but modernised approach).

Which one are you considering to get? My Stagea came with the Fujitsubo Legalis R. I think it sounds pretty good. OEM+. Quiet enough for residential but still has a nice burble to it on overrun. A little bit of drone on the highway maybe.

 

Looking to go custom when I have enough funds together. Things that bug me about it and that I'd like to improve as much as possible:

- It hangs pretty low. Often a bit of a butt-clencher on Australian driveways as it scrapes.

- Better flow. This one is okay at 260awkw but my tuner was saying it would definitely hold things back if looking for more.

- Drone on the highway is a bit annoying. Nothing like loud exhausts but I'm quite picky.

- Not a fan of the cannon look

Hey LateApex72. I'm in the States too. I have a '98 260RS. What part of the States are you in? Like soviet_merlin, I have an OEM+ (HKS brand) that has nic burble, but drones a bit too much for me. I think I'm going to replace it. Depending on how quickly you're wanting to move on this, I may have a pipe for you.

What are you looking at to combat the drone? Curious what the magic ingredient is in a custom exhaust to avoid it.

non garbage mufflers, 2 of them (mid muffler & rear muffler).

All** the Jap legal systems have a 2.5" restriction in them somewhere. This is on top of all the other reasons to not love them. A nice big centre-offset muffler in the middle and the biggest muffler that will fit in the rear is usually sufficient to keep even a 4" system civilised. Subject to Dose's stricture on the mufflers not being cheap shit retail part shop garbage, of course.

**May not be completely true, but is near enough to true to stand as stated.

Thanks to our soviet_merlin above, I found a pic of the differences in the two Stagea series' exhaust systems. The piping looks different between the first and second mufflers. Looks like your 98 system will likely not work on my car. Still looking into what will work best (including custom).

Bummer. Was hoping maybe we could both help each other out.

Good luck with your search. Let me/us know what you land on.

Hah, not sure yet, I don't know much about exhausts. At this point I was going to talk to the same fabricator that built @Dose Pipe Sutututu's system for his Skyline. As the others were saying I presume some kind of muffler and resonator combination. I also doubt I'll get around to it any time soon. All money put aside for nice to have things on the car ends up being used for more important issues that pop up.

Would be curious to hear what people end up doing
