Hi, looking for people's advice/experiences on the mentioned exhausts as I'm in the market for a 3" system for my newly built race car but can't decide, would have to be able to support 500bhp and be relatively track friendly (pretty relaxed where it will be used). Any info or advice would be greatly appreciated

Cobra, Japspeed is just cheap Chinese tin rubbish.

They do a track friendly system too with a nice tail pipe

Both are cheap rubbish. Get yourself a nur spec or an hks hi power.

Just seen the track friendly bit, that rules out the nur spec.

Nur spec sound Crap!
Revolution systems are made by Jetex in Scandanavia good quality and reasonably prices

Agreed nurspec are the typical chavtastic 'hey look at me I have a huge mouth and my big angry car with a spoiler which has 4000bhp'

Agree with Jetex, fantastic quality, the only thing I found with the Revolution system was that it was too quiet, I want to hear something so i know what my engine is doing. I remember Duncan Race Dynamic saying the same when he mapped one of mine..

Theres quiet, then theres Revolution quiet!

Great to hear this trinity. I haven't had mine on the car yet due to it still being in 101 pieces. I love quite exhaust I'm like an old man. If I could still get away with running as tabard one I would

Hah, I too like quiet exhausts, had my days with the BRRRRRRRRRRR, now it just gives me a headache.

You will love the revolution, I fitted one to my Type R a few years back and apart from general engine noise, I couldnt hear anything. Was just a little too quiet for me, but peaceful! I moved to Hayward and Scott with the small box, which was a good noise level but a bit too droany.. was almost going to go for the Cobra large silencer one, but ended up with a Genome which is perfect.

A friend of mine uses a HKS silent Hi Power on his Mitsu, and its deadly quiet as well, but very expensive, and its cracked twice. HKS replaced both times granted, shows good customer service but dosent show very good quality in my opinion

I've got a cobra track friendly which I highly rate it's been on the car nearly 3 years. However id advise mating it to an RCM down pipe which will require them to change the flange, not a big job & they did it FOC.

Milltek just like the other crap imho.

Welds all cracked, flanges were shot, I ended up cutting it to pieces and making one up all slip jointed, even the centre box rusted to hell and cracked the welds all the way around, only decent thing to be saved was the downpipe.

I personally wouldn't spend the money on one, yet the cobra we fitted is still pretty much the way it was when we fitted it, work that out

You can always spend the money and go with Hayward and Scott if you want a top quality system

Thanks for the opinions guys, tbh I'm not bothered with big brand names and there bling as the car will be for competion use and not a show car, just after a good free flowing 3" system that can happily support 500bhp, thanks again for all your help

Just had a 3" Cobra downpipe fitted, it nearly touches the floor. Had to raise the coilovers a tad. Did you bin yours?

It sounds well with my Blitz Nurspec back box, dump valve, induction noise, screaming turbo and loud gold wheels.

Coupled in with WR blue paintwork, huge scoop and gargantuan boot spoiler my car really stands out, but I suppose this is more what the Scoobynet community aspires to;

Revolution 3" Track friendly system sounds great when you want it too.

Revolution on mine ..... Don't sound too shabby I think.

With equal lenght headers...

Mine never sounded like that!

I have a full decat japspeed system on my newage and it sounds lovely nice burble on normal driving but comes to life when you put your foot down. As for it being cheap tin maybe it is but I have found it good enough for me and good value. I have had numerous exhausts in the past expensive and cheap and they all do pretty much the same thing in my opinion just give different notes and sound levels. If you want a quiet exhaust (no offence to anyone intended) why buy a Scooby, they should be heard coming from a mile off the cars are famous for their noise so why tame it? Just my thoughts.

As per we get a whole host of people who have never had either commenting and offering expertise on things they don't know about.

I have a japspeed full exhaust system on my 535hp classic that is reguarly raced and tracked. Never had any issues with it at all. Its dented to buggery and scraped to hell due to the car been so low.

Still performs perfect, no restrictions and isn't silly loud like a chav tastic nur spec.

I have the 3" version. Highly recommended and definitely not upset when I scrape it as it didn't cost the earth!

Had a cobra system on my 2010 hatch sti I swapped the original because as you know the oem doesn,t make much noise let alone give out the famous burble,I must admit I was really surprised by the quality given the price.

I have a tsl pulse extraction exhaust on mine, a nice sound, but I would like it to be a little louder.

It looks well made and very strate

I've still got the down pipe somewhere. It's more about the design of the down pipe with regards gas flow, I just feel the RCM is superior so I chose to retain mine & reflagged it to fit with the rest of the system.
