resonators don't do much.. what you need is a mid muffler..

the HKS Super Dragger is a decent exhaust, has 1x large mid muffler, followed by a resonator, then a massive cannon. I got one recently on my current car and I love it.. not to mention the pipe is about 3.5" wide

Does anyone have underneath pics of the mid and rear muffler space of an R33 . I believe they don't have a lot of space and it would be good to know how big the oval mufflers can be . My exhaust is some sort of Nismo the car came from Japan with , pretty quiet and I'm curious to know what they've done to shut it up . I think most Jap exhausts would be 80mm because they can't replicate (metricate) 3"/76.2mm .

A .

You can fit 16" x 10" x 6" as the rear muffler, the centre muffler needs to be smaller in every dimension. At a guess I'd say 12" x 8" x 5" - even that would be maxing out the space. The 2 x 2.5" Fujitsubo system I have lying in the garage has pretty much the biggest mufflers possible in each space. I thought it was too quiet (And so did my friends) so I replaced it with a 80mm Apexi Bomber (copy) which drones at 2500-3000rpm as you would expect.

You could eliminate most of the drone with a side-branch resonator, or a big oval muffler (with resonance chamber). But a big muffler will cost $400+.

      Certainly. It is probably broken under the wire style clamp. At least that one is easier to get at than the front one.   Sounds like it isn't a major leak, I'd start with backing off the the water feed and return banjos into the turbos half a turn then tightening properly. Hardlines can still crack over time, either in the tube (particularly when turbos are changed if the banjo is siezed in the the tube) or at the brazed joins between the lines and the banjo fittings. A coolant system pressure test will reveal all. BTW you'd be able to get a sump without exchange, it will just cost more as they will have to source another stock one for the next customer. If you want to address the sump a much better option is something like this https://www.hioctanedirect.com/hi-octane-racing-sump-extension-nissan-rb26 that you weld in locally (and add the oil return fittings at the same time)

      Pretty sure you are thinking of the throwout bearing there (which you should change when you change your clutch), when they are worn they will get quieter if you put your foot on the clutch. An input shaft bearing is turning/noisy at all times.

      I’ll have more of a look into Recaros over the weekend. It’s taken me 2 days to figure out which Bride seats suit my application haha.

      I am aware of their presence, but the product page looked like that conversion will eliminate the AWD capability. Fact remains it's kind of a hassle to send my oil sump halfway around the world and buying an extra one is expensive and unnecessary. Before I go hat route I'd explore more local options.    Would you recommend I just pull the engine and renew as many things as possible since I'm already having problems with some leaks? Would have to get an engine crane first though.

      Shifting questions

      Are there any indicators that the vehicle is in limp mode?  Any dash light, or something.  Or is it just lack of acceleration?
