Installed the grills today couldn't be happier. Really improved the front end
J.W.
First titanium exhaust I have owned and best choice I've made, quality and price was half price of everyone else. Absolutely love it
E.M.
Both the grille and downpipes were great fitment and quality. Best bang for your buck. Service was great. Downpipes cannot go wrong for the price look and fit great. The car with the new downpipes sound amazing, truly opened up the already amazing sound of the car. Had it tuned and it drives and sounds amazing.

Got the heat shielded catless Downpipes for my g80 m3. Fitment is perfection and the sound could not be better. Very high quality construction and great communication with everyone at GCA.

Steven Molina.
Great product and very helpful staff! Cleans the look of the car.
Ronald Lorek Jr.
The wheels came out amazing. Was a little hesitant because of the lack of photos of different finishes and such, but the guys at GCA were super helpful and I got a rendering of the wheels before they started building them. I went eith the premium matte brushed 19x9.5+25. They were built to my exact spec for my S5. Not a bad deal at all for the price/quality, and you1re getting a wheel that pretty much no one else has. They also gave me the upgraded center caps at no cost which was a nice bonus.

Open up your Z4 with this Valved Sport Exhaust System, built for the 2019+ G29 BMW Z4. With the push of a button you can go from valves closed for your daily driving, to a deeper, harder-edged note when under real load.
Designed in-house under our GCA Performance line and built from stainless steel and titanium, it's engineered to flow harder and cut the back pressure where the stock system chokes - freeing up horsepower and torque the factory left on the table.ย
The weight savings over the OEM setup help the back end of your Z4 feel lighter and more eager, too.
It fits the G29 Z4 across both engines - the 2.0L B48 four and the 3.0L B58 turbo six - so whether you're running the sDrive30i or the M40i, this is the system that finally lets the motor sound like it should.
Material: High Quality T304 Stainless Steel/Titanium 6AL-4V Grade 5 Titanium
Includes the full Cat back Exhaust (Mid Pipe and Axle back portion)
Includes dual exhaust tips (or quad exhaust tips if preferred)
Electronic exhaust valves with controller for factory-like operation
Precisionย TIGย welds for high strength and perfect fitment
100% Reversible, always able to go back to stock at any time
*Comes with ALL necessary mounting hardware*

First product I purchased from German Car Accessories and I couldnโt be more happy! I have zero complaints shipping was never easier and I was always updated on progress by production team. The quality of the stainless steel was amazing and installation was very straight forward. This exhaust kit has brought so much soul to my car and canโt wait to get behind the wheel everytime. Thank You GCA for the discount code and canโt wait to order again!!!
