Only Authorized Dealers Sell GENUINE ZTEK Exhausts. This Exhaust will bolt up easily and perfectly, very firmly installed using factory existing mounting points, directly replacing the stock muffler. A ZTek Sport Exhaust system will give your car a rich flavored idle sound, and at WOT your M3’s newly acquired sound will be music to your ears. WOT and firm acceleration sound is deep and throaty, reminiscent of more powerful F1 race engines, while at cruising speeds, there is no resonance. ZTek Mufflers are made from the strongest 14 AWG Fully Mirror Polished SHOW-QUALITY Stainless Steel, weighing in at only 26 lbs!! Saving over 30 lbs from stock! Your M3’s handling will be noticeably more nimble and responsive due to the weight savings, cutting track times and making your driving experience more enjoyable. ZTek Mufflers feature straight through design for the least amount of backpressure, nearly half of stock, leading to noticeable power and MPG gains. Customer’s dyno's have seen increases of 10.6hp and 9.5 ft/lb torque on a stock E46 M3, with just the Muffler swap. Although on a stock car they work great to increase horsepower and torque through the entire power band, it is HIGHLY recommended to pair these mufflers with ZTek Headers for even more significant gains in power and an even more unique sports car sound.
