Guys,

I have a 2004 2.0 WRX PPP, and just bought a 2006 2.5 also with PPP. But its a lot quieter than the old one!

Is this normal? Or could there be an issue with my new car?

Any low cost tips to make it a bit noisier?

Cheers,

Jonathan

 

Nothing wrong, its just that the 2.5 is just quieter.

I changed fron a MY05 2.0 STi Type UK, which had a lovely burble to the MY07 RB320. The RB has a nice sound, just not as good as my old Type UK!

A low cost tip would be to just change the back-box to say a Blitz Nur Spec S, or for full on burble get the Spec R.

I'm sure that the masses will be along with all sorts of exhaust option soon.

 

De-resonated centre pipe.

 

Nur spec and HKS SSQV - job done

 

Thanks for the quick replies guys.

Where can I find more info on a de-resonated centre pipe? Is it a mod to my existing one or a replacement?

Cheers,

Jonathan

 

As norman dog said - you need to get shot of the resonated pipe (the bit that joins to the back box). I tried allsorts on mine, but when I change this pipe for a non resonated one (£99 I think ), it was that that made the big difference. Mine now has a deres pipe and aferburner vortex back box and sounds perfect imo. Even pops nicely too

 

Anyone such as scoobyparts/tsl/revolution etc sells them. Or even ebay. Its only a shortish peice of pipe that is straight through. Your existing pipe is the part that looks like its swallowed a hot water bottle!. No remap needed etc

 

full decat and remap, jobs a fish

 

Thanks again guys, this is really helpful.

I found a replacement pipe here Scoobyparts Ltd TORNADO NEW AGE REAR PIPE which looks like it might help.

It strikes me that anything involving a remap at this stage could be quite costly.

Cheers,

Thats the part. That will give you the burble back. I just had a remap, without decating or changing to a sports cat and even without changing those bits the difference is amazing. The car is much smoother and is now producing 340BHP/360lbs/ft. A decat/Sports cat would see more again, but funds wont allow it!!

 

Thanks Luckyscoob, sounds like replacing that is a no brainer. I'll go for one of those, and then look to see what else to do after that.

340bhp on yours sounds exciting. I'd want some brake / wheel / tyres upgrades on mine to handle that. But given its subtle looking Sportwagen, I could have some real fun scaring some of the local Chelsea footballers in their flash cars! http://images.ibsrv.net/ibsrv/res/sr...ies/tongue.gif
