The Dinan G20 330i / G22 430i exhaust grants the B46/B48 4-cylinder improved exhaust flow by reducing back pressure, and also creates a deeper and fuller note, without any added drone or other negative side effects.. The goal of OEM+ and then some. Utilizing factory cut points and mounting mechanics this Dinan exhaust system is a straightforward install with fitment like you would expect from the manufacturer. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. For those that wish to have options to limit the soundtrack for late night or early morning arrivals/departures, factory valve control is retained. No matter the situation the Dinan valved axle back exhaust system is the answer for the discerning enthusiast looking for performance without sacrifice. Max HP Gain4 @ 6600 RPM - Max Torque (lb-ft) Gain3 @ 6600 RPM Features: Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Dual 4" (102mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (85mm to dual 60mm vs. 85mm to dual 83mm) 100% 304 Stainless Steel construction Retains factory valve control Factory-like fitment with included mounting hardware
