Evening all.
I currently have a full scoobyworld afterbuner vortex system on my scoob and dont want to change it really. But its too loud for track days and the bung when used on the road is costing me around 30 BHP.
So Im going to buy a second back box as changing it only takes 5 mins anway, so what it the best performing and quietest back box on the market today for a classic?

No takers then?

 

Get a racebox from scoobyworld, they are similar in sound to the ppp backbox.

 

Are they as free flowing as the afterburners?

 

I can never get my bung to stay in properly on my afterburner. Didnt realise they rob it of performance tho.

Try a prodrive BB. They can be had on ebay for £50. Still sound nice and reasonably free flowing.

 

I currently have a Racebox on my hawkeye STi. A mate had his car, the same as mine, mapped with a Vortex and full decat. He made 2bhp more than me and my Racebox and a decat. So not much in it based on that.
