Ok well some of you may know that l had a Yozzasport system fitted to my 197 with a Yozzasport decat pipe.
I recently returned to JP Exhausts (Actual manufacturer for Yozza) for them to fit a 100 cell 4" metallic swedish made sports cat and centre resonator box. The reason for this was:
A - Legality
B - To iron out some power delivery issues
Well apart from solving the above problems it also had the added bonus of giving me a huge lump of mid range torque. Has anyone else experienced this? To me it seems quite clear that the lack of back pressure due to the de-cat was losing me a fair amount of torque.
I should also point out that when l had the de-cat fitted l had an RST custom map (to cope with the de-cat) and afterwards l've reverted to an RST map designed to be used with a cat.
The car is SO much better to drive now! Well chuffed. :D
