Catless AA X-pipe & Eisenmann Race

tomvcarter · 06-04-2010, 04:09 AM

Hi,
Has anyone got/heard this combination, currently got a Race muffler, and been offer a used AA catless x-pipe.
Would this be insanely loud?
And would i notice any performance gains?
Also would i need any software in order for the car to handle the x-pipe?

Dropping both of those cats you should feel the performance gains with all 4 cats gone of 20-35whp

You don't need software you will just have a CEL light for no cats. But if you get software it will take the light away and you'll make a bit more power to take advantage of the full exhaust.

Get an ESS tune
