sonofsam 5 Posted May 30, 2006 Im sure Hilgie mentioned a 'Laser' backbox as being 2.5" straight through design. Im using a Janspeed box, its just under 2.5" at about 61mm. Are you taking out the middle box? Share this post Link to post Share on other sites

Are you taking out the middle box? Lasers are indeed of open design and good built quality.... but a laser is somewhere like 58 or 60mm... anyway enough to let your gasses flow.... and with the 2.0 turbo you dont need a middle box anymore just a straight pipe of 70mm Share this post Link to post Share on other sites
