E46 M3 Performance Valved Cat-Back Exhaust:

The wait is finally over, if you have been driving your E46 M3 around with a stock exhaust or are looking for your final exhaust setup we have you covered! Welcome to the world of ingenious designed exhausts that can meet your every driving need. Our new E46 M3 catback Exhaust is a stunning example of both engineering and art with sounds to please your ears and a sight to remember. Our catback is a lightweight and free-flowing exhaust that features two independent valved mufflers and a brilliant mounting system that is a pleasure to install and easy to perfectly dial in the exhaust fitment. Weighing 19lbs or less than your factory exhaust, featuring mufflers specifically designed for the S54 this exhaust is able to provide two completely different driving experiences.

With the exhaust valves closed the refined driving experience will blow your mind; while daily driving with closed valves there is a perfect bump in volume over the factory exhaust which allows you to hear and feel your rpms with a smooth exhaust note that shows your true passion for your iconic vehicle.

Now on to the real action, what you have always wanted but never wanted to commit to. Some days you just want to put the pedal to the floor with unlimited amounts of exhaust volume with your high revving 6 cylinder. Here is your opportunity to unleash the pure sound of your S54 while having the choice to change back to a respectable volumed exhaust. With the valves open this exhaust is an absolute symphony. Starting off from a stop with the valves open there is a significant increase in volume over the valves closed. When entering in to the 2000 rpm range you begin to experience the slightest taste of how satisfying the exhaust is going to sound. As you approach 4,000 rpms and higher you now have started to open up the can of worms, you can feel the free-flowing path of the exhaust with limited to no resistance, far superior to the factory exhaust. Anything after 6500 rpms is an absolute statement of exhaust. Over 6500 rpm is a sonorous note that lives rent free in the enthusiasts mind that can make a believer out of anyone who doubted the capable E46 M3. Once you are done having your fun and have experienced your S54 more than you ever have all you do is make one button click on your valve controller and you are back to high class and refinement. Truly the best of both worlds and a school girl giggling experience anytime you want.

PRODUCT DEVELOPMENT:

Our Turner E46 Valved Catback was designed, engineered, tested and quality inspected by our Research and Development team at Turner.

E46 M3 Euro Style Carbon Front Lip:

Our unique and carefully designed front lip for the E46 M3 focuses on enhancing the car's aesthetics while preserving its natural beauty. This front lip is constructed of high-gloss, 3mm thick, 2x2 carbon fiber that adds a tasteful accent to the bumper while being strong and lightweight!

This aesthetic piece was crafted to stand out from other options available on the market by incorporating design elements that draw inspiration from the stock bumper but reimagines them in a way that sets it apart. Rather than overcomplicating the car's body styling, the goal was to seamlessly integrate the front lip with the existing design. This approach aims to enhance the car's body styling rather than overshadow it.

This versatile design is suited for both track use and everyday driving on the streets. Our E46 M3 front lip was designed to strike a balance between uniqueness and performance oriented aesthetics, while complementing the car's existing design. This is a clear cut choice front lip for someone looking to enhance the look of their M3.

Once you see your M3 with this front lip from, you will no longer think the front end is complete without it. Rounding out the near perfect car, this front lip completes the front end by filling out the open space underneath and sets the stage to enjoy the timeless body styling incorporating a curvature that compliments the front bumper.

Features & Benefits:

High-Gloss
Beautiful flowing carbon weave
Strong and lightweight
Updates the bumper with carbon appearance that enhances the existing body lines
Motorsport styling
Enhanced lowered appearance
Design:

CAD designed in-house for precision fitment
3mm 2x2 carbon fiber shell securely mounted at strong mounting points along the whole surface where the lip mates to the bumper
Front leading edge helps compliment and accentuate the forgotten body lines to add an aggressive yet subtle flare to the front end
Attaches to the front bumper with self tapping screws, plastic riv-nut and 6mm 3m adhesive tape to securely mount
Installation hardware included

A Do-It-Yourself exhaust install can be hard enough. But to stop in the middle of it to run to the dealer for gaskets, hangers, or special hardware is a major inconvenience. Don't be left taking the bus to the dealership on the hunt for parts. Get all of the parts you may need before the job begins! And with mileage we can almost gurantee that any section you remove will need to have new gaskets. Some of the gaskets are crushed to ensure a tight seal; other gaskets become stuck to their flanges. This set of hangers and gaskets for the 2001-2006 E46 M3 covers all of the sections of the exhaust, from the headers to the muffler.

The exhaust on the E46 M3 is broken up into sections -
headers - gaskets at the cylinder head and at the outlet to section 1, plus an air pump gasket
section 1 - crush gasket rings on the inlet and flange gaskets at the outlet to section 2
section 2 - flange gaskets at the inlet and steel exhaust rings at the outlet to the muffler
muffler - steel exhaust rings on the inlet with special square-shouldered nuts (included with hanger/gasket kit)

This package also includes 3 new muffler hangers and the 2 hangers in the center of the exhaust (mounted on section 1).

We also offer most of the exhaust hardware you may need -
Torx bolts and nuts for the header-section 1 connection
copper nuts for the section 1-section 2 connection (M8x30 bolts can be re-used)

Applications:
2001-2006 E46 M3 coupe, convertible
