Has anyone bought a Japspeed cat replacement pipe? they don't have the cel fix bit though

 

buy Berk Technology you wont have a problem. I looked at Spoon and J's and both seemed not to have a CEL fix, this can be bought separately but will end up costing you more than Berks which by all accounts is high quality..........

 

Yup, bought one and a fine fit

You just need to pickup an anti-fowler for the sensor and you're off

The Berk is also quality

 

where did u get your anti fouler
