The Alpha Mercedes-Benz A45 AMG Cast Downpipes are the best performing and most durable on the market! During testing our shop CLA with our Alpha A45 AMG Downpipe, Filter, and Alpha CLA Tune our Engine Calibrators saw amazing gains across the power band in both wheel horsepower and torque! The power came on earlier and carried over 100 ft lbs of torque gains from 2900rpm to 4850rpm!!! Turbo spool-up was significantly improved! The long gradual transitions within the cast down pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system!
Big power increases throughout the power band
Improved turbo spool and throttle response
Cast construction offers added performance and reliability over the competition
Throaty exhaust note under wide open throttle but subdued at idle and while cruising
Comes complete with form fitted heat shield to keep ambient heat to a minimum
Stock like fitment with no chassis clearance issues
Bolts up to the stock mid-pipe or most aftermarket systems
Precision TIG welded with unrivaled fit and finish
Heat shield tastefully logo-ed with burnt titanium logo
NOTE: The Alpha A45 Downpipe flows so much more than stock that an Alpha Performance tune is required. Turbine efficiency is increased due to a larger pressure ratio between exhaust manifold and the Alpha Downpipe!
