Can anyone recomend a good backbox for a 2003 JDM twinscroll ?

I'd love to get a bit more burble back !! Twinscroll is great but not enough growl....

Currently has gas flow downpipe. not sure which but looks like a Trust one. Standard mid and back box.

Looked at afterburner vortex and scoobysport (but they never reply to emais for some reason)

Thanks.

 

Afterburner vortex much louder than the scoobysport backbox,brilliant sounding system imho, I've had 4 of them .Buy one you wont be disappointed

 

The best system out there which will give you the best gains and the burble to is an RCM system it also looks great to and not like a massive drain pipe hanging of the back of the car.

 

I have a genome backbox with straight centre pipe with no resonator on my jdm and think it sounds great, it screams on boost but quiet around town. Don't think you will get a burble on a twinscroll just need to take advantage of the onboost howl.

 

Fujitsubo system sounds great on twinscroll setup too
