Haven't fully tested it yhet, but will i see a LOSS in performance with a scorpion backbox compared to the original vauxhall box?
Just thinking that as it lowers the back pressure....

Ive just swapped from a Powerflow system exhaust, no middle can and just a wee small can at the rear, to a standard center section and Sebring 6 x 4 rear box. Firstly its MUCH quieter and my car pulls away MUCH better but i have noticed that at top end its lost some torque - thats on a 1.2 16V XE little lump.
