how loud is the blitz nur spec r with bung compared to my non res aterburner centre and ninja back box, will i get any power increase with the blitz ta

wot u got now is probably really raspy
i had the blitz and changed it for similar to wot u have . .

now,i've gone for a firestorm and TSL resonated centre to keep
the sound but get rid of the harshness . .
the blitz is loud but not raspy,but is also 3" bore,where as wot u got is 2.5
you wont notice an increse in power as you are still de-catting the centre
but get it re-mapped and you will ;-)

ps,get a knocklink as well,just to keep yer eye on any detting.

the flange is 2.5 to fit the down-pipe then its 3" all the way back
