ReMap E92 M3

I'm wondering is it worth remapping my M3, I have a challenge sport X pipe and Eisenmann back box but wondering if I got a remap and when I have to put my old exhaust back on would it damage the cats??

Also where would you trust to do a remap, I was looking at an Evolve remap but at €1k it's jut silly money really..

Thanks

What about talking to someone like Martin from Autoremap?

As above have a chat with Martin

Yea I had my E46 M3 with him and got the airbox and remap and it was €1k for an evolve remap and I'm not sure I'm willing to pay that for the gains, have a few other bits I would want more..

I'll chat him anyway maybe he can advise me anyway.. Cheers

I can get this beast remapped.But dont expect much,-like from diesels or turbo petrol's.
