Upgrade your BMW B58 with the VRSF 4.5 inch stainless steel downpipe for a serious performance and sound transformation. This premium brushed-finish downpipe is available in both decat race and 200 cell high flow catted versions and is one of the most effective, best value bolt-on modifications for BMW M140i, M240i, 340i, 440i, 540i and 740i models including xDrive. Expect faster turbo spool, lower back pressure, increased power with a tune and a deeper, more aggressive exhaust note.
