New R36 cat-back exhaust

[Martin Donnon]

Why would one 'chop' part of a dyno chart off to display?
You know if you select the main channel or overlay channel on your Mainline dyno as 'Torque' set the Channel Properties to 'Derived Torque' as use the OBDII Tacho Pickup you will in fact -

1) Get a nice full size screen printout of the torque curve
2) Have it referenced by RPM
3) Obtain a torque figure that is accurate (as per the rpm input)

Print that graph again, dont chop it in half, and it will make more sense to the users here

I don't know.

I am hearing a high pitched clicking in amongst the exhaust noise. Like there's a loose marble or ball bearing clicking about. It might be an artefact but it's definitely there in the recording.

Otherwise the noise is OK; but to be honest I think the stock exhaust noise is pretty good too. I had a Remus exhaust on a past car and after a few days I had regretted it. Took 2 years to burn a hole in the muffler and I got the stock muffler put back on. Now that Im older I think the subdued noise that shows some refinement is best for me. Each to their own though.

What to do??
Liminary, you're spot on. Surely it's maturity - NOT age. It's mega $$$$ for an exhaust that may be too loud, not sounding right or made for "jabbers". This exhaust is big $ and too high for any mistake. Are there any other options? Surely there must be another option.
I would like my R36 to sound a little more meater and just a little louder - like an R32??
What to do??

The exhaust alfie had fitted by Evolve-Technik sounds great. If you're in Melbourne you might be able to arrange a meeting if you PM him

the biggest concern i would have about any non-standard exhaust is in-cabin drone.

[Autopia]

Alfies car sounded great inside. No drone.

Lol thanks mate.. You should hear it now with the new air filter i just fitted...

Do you notice any difference with the intake?

Do you have an idea on you engine out put now (FWKW) after all your upgrades?

[Autopia]

Lol thanks mate.. You should hear it now with the new air filter i just fitted...

Man you just never stop do you?
I'll have to hook up with you again and have a listen to it.

lol nope.. there's never enough... Just Pm me if you wanna meet up.. That goes to anyone here on the forum btw..

[Black R36 Sedan 09(alfie)]

rays 5150, the estimated Kw out put at the flywheel after the tune and catback
was at 252Kw. Peter from Evolve has this complicated formula that gives a rough estimate.. But after that i put in high flow cats and the latest addition is an high performance air intake system.. so it might be at the 260Kw mark or there abouts..

[Rocket36]

Would be worth pulling it and hooking up an engine dyno at some point.

[Black R36 Sedan 09(alfie)]

yea... but damn.. its a lot of work pulling the engine out, and hoking it up on the dyno... i will i guess at some point mate.. i am currently working on a new plan for the car.. Playing around with the throttle body. I am trying to apply what they did to the M3 CSL to the R36.. Potentially it can increases power output up to 50%.. But then again, word of the day.. "POTENTIALLY"

The production version of the R36 cat-back exhaust is now available. A lot of effort has gone into getting this version just right, ..no drone, no booming, and still sounds brilliant. With an order of 5 (contact us to confirm), this system will retail for $2,350 incl GST.

Jesus Christ! Why so expensive for just a cat back?
