hi people just wondering does a resonator make a lot of diff as got 1 in the center on my blitz nur spec r and its no way near as loud as my vortex system cheers rob

 

Yes if you have resonated centre pipe,its much quiet.If you get centre pipe without resonator,will be Nur Spec much louder,but everything depends if you have decat downpipe.

 

Have you got the nur spec R or the nur spec S, as the S is quieter than the R,and as mentioned above do you have a decat .Sorry but i have a full decat and straight through centre section mating to an afterburner vortex and on tickover it is louder than my mates nur spec r,but as soon as the revs rise the blitz is WAY louder.The vortex is loud ,but managable..The blitz is just hardcore,and after driving my mates car for 3 days ,i found myself fitting the bung to stop my head pounding.

 

lol i noticed that the idle on vortex is very loud.sorry yea full decat mate.It was bob5 s exhaust he said it is nur spec r how u see the diff?

 

Hi mate,

Exhaust was tested at Mira with a bung at 105db static, dare not think what it would record without it, it's loud1

It's a Nur Spec R.

If you want to go even louder, a straight pipe from RCM is cheap enough and as loud as you can get (no silencer).

 

has anyone done any performance tests with the various exhaust systems,i have just replaced my full 3" vortex system with a full 3" nur spec r and the difference in performance is very noticeable.The nur spec r is louder and sounds better imo,but does not perform nothing like the vortex i had on.The car spooled up and pulled much quicker with the vortex on without a doubt,im even considering going back to it the difference was that great.

 

If you've noticed a performance difference its coz even changing exhaust or airfilter warrents a remap. Its an expense thing to do and really you'd wanna do a few mods b4 spunkin out to do a remap, but to get full potential out of your new exhaust, you need a remap.

I had a Nur Spec R and hated it... its on loud 100% of the time and deadly on long motorway drives... you need to take paracetamol after those kinda journeys, lol

 

Rob, I got my old 3" system for sale if you want it?

 

i got the resonator cut out no diff? how u know the difference between the spec s and r it seems quiet compared with my old vortex and friends exhausts

 

i have a 3inch powerflow blitz copy and it is loud as ****! car alarms go off. tunnels echo like never before, and if i warm the car up at the front of my house the vibrations make the knocker at my front door shake lol.
It's far too loud for my liking. stick with what you got

 

i only use it w.e s mate so like to wake the neighbours on sunday morning lol
