I have the SS backbox on the P1. I've often wondered what aural/performance/driveability increases would be gained from spending £411.25 at SS to have these bits fitted...

 

Doh! I can't spell either & you can't edit the title....

 

Had SS downpipe put on last weekend along with the rest of a 3" system and noticed a significant difference in performance.

The main change is that the car seems to really pull from a lot lower revs now than it did before.

 

well worth it. http://dyno.scoobynet.co.uk/index.htm is the site to go to. It shows what difference all the bits make.

Hope this helps!!

 

Anyone got a soundbite of the scoobysport bb on a WRX? Does it sound as good as on the old turbos?

 

Will the HKS be as good or better ?
