Yup, agree. I too prefer the nismo. For my car it's a bit overkill anyways. I couldn't see anything when I looked down a legalis, where as the nismo defiantly had the step down in it. Just goes to show, if you want outright and performance, go and see a fabricator like Scotty, then you know what your getting in regards to size. The GTR guys found this on their jap systems too!

The twin Nismo is 70mm internal to the muffler, where as the Fujitsubo has twin 70mm in the rear muffler. Theoretically the Nismo should be quieter then. I wonder how much it will restrict flow...

Hey guys just did the brake cut mod today (simple and cheap) and after having the stag for around 8mths the need for more power is starting to arrive. I think exhaust is next but I love the fact my m35 is so quiet but spanks most cars with no fuss so I'm thinking dump pipe but the rest of exhaust standard? Will this give a good increase in power or would a full exhaust be way better? Money is also a bit of an issue as I don't think the missus is fully buying the " it's for better fuel economy line". Any advise would be aprechiated.

If you were looking at doing one part of the exhaust the dump would be it. They have an extra Cat in them that really just doesn't flow. But really to take full advantage you would want to put a full system thru.

There are some quite exhaust options, for example the single outlet nismo that I have. It's not much louder then stock.

I did a 3" dump pipe on a standard exhaust, and it does make a difference; the stock dump is massively restrictive.

I'd advise a dump & front pipe with hiflow cat in 3", then reduce to 2.5 and into the stock system, if you need to keep it under the radar with the missus.
There would be a good gain in kw and torque, but virtually no change in exhaust note.

Has anyone ever had a resonator installed on their M35? If so, how did you go about it and what were the results?

I've got a Kakimoto R catback with custom dump pipe and front pipes but it's just too loud.

I'd like to add a resonator but was told there isn't enough straight sections in the system to fit one.

Any ideas?

Cheers

A resonator? What you want is a Helmholtz chamber, like the Nismo/Fujitsubo cat backs run. You won't find many exhaust shops that know what they are...

Easiest way is to fit a Varex muffler on the end, or run an active exhaust valve with a bypass muffler.

Do you still have a Cat in your set up?

Just asking as I have picked up a Kakimoto N1 and am wondering how loud this is going to be...

As Scotty mentioned Helmholtz chambers feature on a few M35 Jap shelf exausts, fujitsubo one looks like this.

Maybe see if you can get someone to fab up one for you?

Thanks again Scott for that. I did consider the Helmholtz chamber but thought it would cost too much to fabricate a custom one.

I might ask around more.

Dmyze - Yep I have a cat which is connected to my front pipe. The Kakimoto R is pretty damn loud but it's the cabin drone which kills it for me.

It's even more of an issue since I have a 2 year old plus another on the way.... I need it as quiet as possible.

Thanks for the feedback guys.

Does a new dump and front pipe do much for exhaust noise?? Bit curious because i wouldnt consider my kaki cat back loud or droney at all really..

If you had a de-cat front pipe it would make a huge difference. both hte cat and front pipe will have cats inside them standard.

The Kakimoto N1 is loud as f**k lol, Excuse my french, i have one on my car atm. The drone on the inside of the car is also loud tho it gives a good idle tone. I can post a video for sound/to see what it looks like if ya like?

      I have a VALCON if anyone wants it, I have no idea why you'd want to have VVT specifically broken out of the ECU as opposed to running it off the FCON/whatever standalone you have.

      Hi Yes we're a bit optimistic we might get something out of sealing up the two pipes of the external wastegate and reactivating the stock one. I believe the orginal stock wastegate was tack welded shut. It doesn't budge and visually looks closed and sealed. The car has noticeably more lag so it could be at least part of the problem, maybe all. It's definately one of the key changes made since last tune. And it's one that's more difficult to fully understand and measure, not like for instance timing or cylinder compression.  Thanks for that feedback, we'll let you know how this progresses. Fingers crossed.   Regards Rob

      Well, I was going to say, "Is the wastegate set up so that it is not leaking?" That's actually a different thing to what you're asking about. In theory, if you have allowed the two halves of the manifold to commmunicate (more than the stock manifold does - which is at least a little bit) then the negative effect should be apparent in delayed spool, not in outrigth power. OK, maybe just maybe, a badly set up twin scroll wastegate "crosstalk" might kill the top end, although it's hard to see how. What is happening with the original wastegate in the turbo? is it sealed off properly. If it's left flapping in the breeze, it will f**k everything up. If it is still there, and can be returned to service, I'd be capping off the external (presuming the two halves can and will be isolated from each other after doing so) and have a go with just the stock wastegate. I have an internal wastegate in my highflowed rear housing. The bigger opening and flapper should be fine to >250 rwkW. So there's not exactly a pressing reason to have the external. Done right, an external will give better results. Done wrong, it might just be possible to have worse results. Report back!
