Does cat delete void ESP?

[lowrider284]

Hey guys im going to purchase a ESP platinum warranty but im concerned about the stealership voiding it over a cat delete setup if i purchase a MBRP exhaust system. Anyone have any input/experience with this?

Just throw the cat back in before going to the dealer. Most of the techs on here work for dealers and don't react well to having their employers called stealerships either.

Sorry just had been bad past experience with dealers especially ford, do you know if the exhaust systems usually have the cat portion removable or would i have to cut a piece of pipe and fabricate something? Thanks

They have a section where you can throw the cat back in.

Ok thanks for your help

Reducers

Gotcha so i would just weld up 2 reducers on either side of the cat then just slip it on when need be? Shouldnt an exhuast system be all welded together and tight?

Use band clamps

Just pulled the trigger on the MBRP 409 cool duals with the cat test pipe for trips to the dealer
