This front exhaust section was developed for our no-holds barred track conversion M4 GTMore project. Loosely based on the factory GT4 exhaust, our front section eliminates the factory secondary catalytic converters found on the street car. This makes the system lighter and freer-flowing. It also eliminates the secondary cats which are likely to be a failure point when used for dedicated track or race use. Twin 6" resonators are included to tune and dampen sound. This section will only be sold for actual race or dedicated track vehicles - seriously.

This front section was developed along with the full GTMore race exhaust but we made it available separately if you choose to use it with a different axle-back exhaust. We have not tested fitment with any other exhausts so some fabrication or modification may be required.

Made in the USA
