Backbox for MY03 STi
#4
Hi Andy
I have a TSL Group N back box (had been on the car for 10,000mls) plus mid section which gets rid of that restrictive cat. It made a huge difference to my Sti '02 providing more power and willingness to rev plus a great sound which was not too intrusive inside the car. The build quality on these units is second to none.
Cost new was £398 will accept £250
