i bought my 2002 sti ppp with a blitz supersound fitted but wasent too fussed about the sound so fitted the standard one back on and what a difference, the car is silky smooth now , when changing gear and just general driving.

without doubt , THE most simple and effective mod that has transformed my car for the measly sum of 35 quid for a used re circ from ebay.

very happy.

so blitz item going back on ebay, or if anyone fancys it then pm me with offers as its in very good condition and working fine.
