Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
1. Mongoose
2. Fujitsubo Legalis R
3. hks silent hi power
4. Phoenix Power Departure 2 105 db limit past.
5. Hayward & Scott
Way too loud!!
1. Apexi Hayabusa
2. 5Zigen
3. Blitz Nur Spec
4. RSR
5. Rogues Revision6
A few exhausts that would be helpful to know.
Japspeed
Berk
Blueflame
KO Racing T1/R1
H&S is an awesome system, had mine for a good few years now, decatted with a satisfying muted rumble and passes noise tests for trackdays easily. Sounds awesome on WOT with the wastegate open.
My Berk with a C2Power stainless downpipe came out around 92dB at that RAF Woodbridge airfield day
Dep II (standard) is probably around the same, although likely to be a bit louder. I've had both on the car and the Dep II has an annoying resonant peak around 3500-4000 rpm that may notch it up a few dBs. The sound of the Berk is much more linear.

I was the red turbo at Woodbridge.
Are you saying you have a berk with a de-cat and it passed fine at Woodbridge.?

Yup-passed no problems.
I remember you Adam, I was in the Caribbean Blue turbo with the big dent with half a bush hanging out of it
Yep I remember, did not know if you wanted to keep the little scratch quite so thought I would not mention it.
I had a goose on the car then, now its a Japspeed and I dont think its going to pass.
I would love to fit a berk, not sure I can afford the extra cost so might end up with a blue flame.
Will you be looking at any more track days this year?
Look forward to see you again at Duxford, it will be a great day with 30 mr2s at the moment.

Traditionally Magnex was always a little freer breathing than a Mongoose, mine certainly sounds very loud when you hit 5k revs, but does it break the legal limit?
I'd be interested to know before being turned away from events.

Ummm, hello?
Anyone?
Dont know what to say, there has been problems with Japspeeds and noise levels on the n/a. For some reason the exhaust come out louder on n/a than turbos.
I have ordered a db meter, so could test it for you if we are going be at the same meets

The 5Zigen Pro Racer has great flow properties with little noise increase. Sounds like a jet plane on boost.
For Sale if anybody is interested??

Turbos have the turbine blades in the way so are usually a bit quieter than n/a cars which essentially have an uninterrupted pipe straight to the the exhaust manifold (if they've been de-catted)
KO Racing R1 tested by Javelin at TSS Rockingham 106 db static test 101.2db with bung, just scraped in their 102 db maximum. Think the meter was a little optimistic as have not been done for noise even at Bruntingthorpe which is 98db static. Will soon be for sale as can,t risk exclusion from the Series.

Just added the RSR, havent had it tested but I'd say its just as loud as a NUR spec possibly even louder.
Add to that Rogues Revision6, 112db at 4500rpm
My rogue rev 6 is really quiet (seems to be anyway ),
A guy at work followed me home on his motorbike,and next day we were talking in the car park he said that MR2 sounded crap and tinny, compared to the size of exhaust he was expecting more (he didnt know it was mine )
Im disappointed now

He is probably too busy overtaking people in 30 limits, and cant hear the exhaust over his.
Do you have a de-cat?

Yes its got a decat pipe fitted
anyway its not overly load inside so thats all im bothered about really ,i had a blueflame before and that was too droney ,and the dep2 pro was too load, so im happy really
you can't just put hayward & scott on the list and say its fine! they do complete custom systems to each customers requirements. i have a full custom manifold and cat-less system on my 3vz-fe V6 with quad pipes from a single transversly mounted silencer (355 stylee) and it burbles nicely and growls when provoked, all 4 tips are 3" inwardly rolled. i would say mine would pass, but then every one of thei jobs are generally different! so hard to generalise.

I saw jonb's (I think) trackcar up at lukes on thursday and he had a Dep2 pro on his car.
Anyone else running a Fujitsubo RM01A? It's meant to be a bit noisier than the Legalis R but is also Jasma certified so it's not stupid loud.
Mongoose
