Quiet performance exhaust - Do they exist ?

[RobEVo5]

Hi,

I have a RX7, which has the Mongose cat back system, and to be honest I am finding it a little bit too loud for me.

Is there a quieter freeflowing exhaust on the market ?

Does anyone have a quieter performance exhaust who would like to swap for my mongoose ?

Does a quiet\'ish twin outlet exhaust exist. i.e like a S2000 pipe each side ?

Thx
Robin

Hi Robin

My Apexi was loud as hell but I always heard that the racing beat cat-back was a nice quite exhaust with good flow.  Maybe someone who has had one could give there opinion.

Been reading and like you say seems like a Racing beat gets the thumbs up. also someone somewhere said about a feed silenced midpipe.

The Mongoose looks like it should be quieter than it is with a small box in the centre section and back box being of reasonable size. compared to a blitz its probably quieter but still very loud for me.

Anyone wana swap a racing beat for my mongoose, with possibly some cash adjustment ?

Feed midpipe is a nice decat that gives the opportunity for more power whilst restricting any increase in noise, also quite expensive.  I had the feed midpipe on mine but the apexi catback still made too much noise at normal revs for me and was boomy.

Hopefully some people with experiences of other systems will chip in.

Thought I\'d add that shyauto\'s do a tiger catback that may be what your after, as I\'ve heard its reasonably quite.


Good luck.

Hello mate! There is a guy who\'s just bought a RX and posted some pics in the 3rd gen section. He says it\'s got a really quiet stainless exhaust on it and he\'s interested in swaping it for a louder one. Think his name is little_ant?
Give him a shout!
If your not a fan of noisy exhausts then think yourself lucky you havn\'t got a blitz nur-spec!
Every time i come home i keep expecting to find a eviction notice or an ASBO for  noise pollution!:rollin

Yep I have a nur spec aswell and its LOUD!! Even with an R-Magic Silenced mid pipe!!

not sure of the make of mine but it\'s 89dB on track!

This is a common topic and for good reasons, whether its the neighbours or track officials!!
Those of us who have the Feed midpipe/RacingBeat catback-i\'m one of them-it is relatively quiet compared to most...Apexi/blitz/HKS etc.
Sometimes i wish i had more flames..commoner with big rearcans..but ,hey ho,cant have it all.:Tongue1

I\'ve got a FEED downpipe, Knight Sports high flow cat and a Fujitsubo Power Getter RS exhaust and it\'s not loud at all.  I read around for ages before buying this exhaust as I heard they are meant to be some of the quieter ones.  It sounds great but just isn\'t that loud, I\'m sure the cat helps as well.

get a kakimoto mate theyre well quiet mostly,i have just fitted one n it aint much louder than stock!.dragon have a twin silenced version for sale as we speak!.

Had a NUR Spec with a silenced center and it was over the top. Went to Custom Chrome in Nuneaton who replaced the backbox for one of their own but kept the unrestricted 3"bore on my strict instructions. 6 db quieter at idle and 5 db quieter at 5000rpm. It still barks a fair bit under WOT but on constant or slight throttle its a lot quiter so you can make discrete entrance and exits and its not boomy on a long run.

Mine isnt boomy on a long run, but idling its LOUD!! I park it in my driveway up the back of my house and go inside to the living room at the front and can still hear it if i leave the turbo timer on.

U\'ve all got me scared now. I\'ve ordered a NUR spec. Sound like after it\'s made my ears bleed my neighbours will be shooting me when I go to work at 6am.

I recently got a Blitz NUR spec and it is definately a loud exhaust both at idle and driving, even with my Dragon silenced midpipe. My old Apexi megaphone exhaust sounds like a standard exhaust compared to the Blitz. I might be putting the Apexi up for sale if anyone is interested....

I\'m afraid I can\'t give you any good news. Mine has a Blitz nur-spec with a decat and even with the bung in it is too loud. I now park on the road a couple of doors down from my flat so I don\'t wake the neighbours at 7am every morning. Without the bung it is loud ON TICKOVER!!!
 
But, if you can avoid your neighbours, the flames are fantastic (even with the bung BTW) :flamed
 
I\'m changing to an SMB twin tip to reduce the noise
