335i info needed.

Alright guy's, so after i introduced myself in the relevant section, I'm sure you guy's won't mind helping me out.

I have a customer with a 335i twin turbo charged BMW..

I build full custom TIG welded downpipes and zorst systems, and this customer has asked me to put together a quote for him, including a twin induction system and some other goodies.

Now I'm not too clued up on BMW's, and I need to know just one thing.

I'm obviously going to have to remove the CAT or CAT's, the customer does NOT want to have software done, and I need to know if a mini cat fooler will stop the car from getting errors??

has anyone removed the CAT yet and fitted a mini CAT??

Your info will be greatly appreciated.

Thanks a million

Philip.
