Anyone recommend a good exhaust system

[WRXONP]

a 3 inch should give MORE low down power than stock - less back pressure = faster turbo spool - exhaust is the key to power

I noticed a lot more low down power and faster spooling with my new exhaust

Amen brother if i was running an rb30 ;) I'd even go four inch given the turbo was big enough ... Are you gonna track it soon bro? When and where? Mind if I tag along?

[WRXONP]

haha off topic as but yeah the turbo is huge if you look at the pics - 3 inch works a charm on it- straight through of course - i would go 4 inch too but the dam thing hangs out allready and scrapes on judder bars LOL - and not sure about the track but hitting the skid pad next weekend at meremere to let it loose !!

but yeah back to exhausts !!! LOL

oh and subarus hahahahaha

Well just dropped loud exhaust of, really light!! Its a ganador full titanium, from the research i have done it should be 102db with out silencer and 98db with, plus the small hole in resonator. Would have been worth a bit at a guess. Bought silent hipower of fastfour, will hopefully get it fitted tomorrow, should be sweet!

Yup im running one after i saw royal sti's car with one not a factory fit on the bugeye due to brackets being out of line in places more to do with bad jigs on the pattern than anything also needed to lengthen mine by 100mm cause i didnt like the fit but other than that flows really well not overly loud but loud enough to know you mean business and helped spool faster if your handy at fabrication its a good choice didnt fit the up pipe that came with it no need really

[WRXONP]

those stainless over sized up pipes are rubbish - i made more power and made power earlier on stock up pipe

Right on exactly why i didnt change it

[urabus4]

Finally got exhaust on and been for a blat, talk about quiet compared to what it was!! I do miss the raspyness that it had but enjoy not attracting the wrong attention around town ;D Will be great on a longer trip with the family 8)

[Fastfour]

When you press the lour pedal down a fair bit it gets loud though

i had a japanese brand name "quiet" type 3" exhaust on my car until a few hours ago. robbed 30kw on the dyno

[johnny5]

Thats a big loss... Take that sucker off

[Fastfour]

Name and shame it sultan.

I achieved 237kw atw on 16psi with the HKS Silent High Power cat back exhaust fitted and rage down pipe so it can't be that bad

Geez wat car do you have and wat mods sounds like your on a good thing

[sultan]

Zerosports. Unsure which model or how old but it has some spiney turbine things in the centre pipe and muffler. In initial tuning car apparently made only 215kw with it at 18psi. As soon as it was unbolted power shot up over 250kw without touching the computer. Now its waiting for the new exhaust to arrive before tuning can really start

Wierd, Simon C runs one of them on his V7 and it's over 250kw... have to see how mine goes on the dyno when it gets there eventually but I'm running one of those venturi turbiney Zerosports exhausts too.

Must be a bit more to it but thats a good power range to be in to much for me and the street now I have kids though hopefully 220 atw when tuned not far now and i should be there
