Check out the Cat Back Exhaust system we have been developing with Kooks Headers and Exhaust. Twelve weeks of design, prototyping and testing with five iterations to produce the high-performance product you will see here. This system is true to the Kooks mission statement of, "Providing superior engineering with performance excellence." If you have been looking for an "M" class level of exhaust sound than this is for you. To hear it for yourself click on the YouTude video link below. https://youtu.be/DyX3CQN9X4M?si=51HA75VlCwYWvvMh We are also testing tuners in conjuction with this system, which you can also see on our YouTube Channel.
The goal was to produce an exhaust that sounded great at start up and throughout the rev range under acceleration while using all the factory mount points so keep labor costs to a minimum. The details came in tuning for decelerations and crisp upshifts and downshifts. The sound is really audible outside the vehicle and with the windows down but within the well-insulated cabin you are still experiencing a quite ride. You can hear the turbo spool at WOT, it's just more subdued in the cab. Another major criteria that Kooks considers is using all the factory mount points for simplicity of installation by the buyer. You can install this in your garage floor or on a lift. The 304 stainless steel system is designed to install with one person at home. There is no welding required, no custom hangers, the system is completely engineered for ease of assembly. Having built and disassemblied the system through all of the iterations we know how to make it easy.

Has a great open rumble at low speed but fades away at hwy speed. The cold start is very throaty then mellows out to a nice sound.
Deceleration has some pops but not a silly amount Super great driveable combo!!!
Seriously, incredibly addition to the grenadier. Much more free flowing than the stock exhaust. Does not rumble or shake at lower RPMs. A lot more spirited all around at all driving speeds. Far more exciting to drive every day than with the stock exhaust. Overall superior quality of steel and exhaust sound. This is a must have.
Just got my Grenadier. This is exactly what I’m looking for to increase performance. I’ll be ordering one from you real soon👍😁 rsjr3355@gmail
