Description Extended Information Post A Question
 
The GrimmSpeed Cat-less Divorced Downpipe is one of the first modifications that should be done on your car! The OEM downpipe has two restrictive catalytic converters, killing power potential. By replacing the OE piece with this top-of-the-line fully USA built Downpipe you will fully maximize your exhaust flow which will increase the ability of your car to produce huge horsepower and torque gains. The increase in power and response is so dramatic that a tune is necessary with this upgrade!

***Replacing your factory catalytic converter sometimes causes a cat converter efficiency check engine light. You can either use tuning to delete this CEL or you can use a mechanical fix.***
