We are proud to offer the Rogue Engineering ELS RASP pipe for the E46 M3! Do you want your car to have a smooth tone below 5000rpm (like the sound of a V6) while the exhaust tone above 6000rpm changes to a scream of a baby V12! This is your unique solution! We hope to have video/sound soon!
Designed for vehicles with the BMW OEM Factory European Exhaust Manifolds (and US BMW catted manifolds), the ELS RASP pipe equalizes the tube lengths at the Section 1 mid-pipe! As you can see in the image below, there is a large difference after merge collectors of Bank 1 and Bank 2 manifolds. This is one of the design traits of an inline-6 engine. This difference in length (Bank 1 is 9.5" longer than Bank 2 after the merge), is part of the reason for the particular sound of the exhaust.
By strategically adding 9.5" of additional tubing into the Section 1 midpipe (on the Bank 2 side), we are able to then equalize the exhaust flow and tone coming out of the exhaust manifold!
The Rogue Engineering E46 M3 ELS Mid Pipe
By equalizing the exhaust flow as it exits the Section 1 midpipe, you now have a smoother sound without sacrificing power, weight or fitment!
Specifications:
- Designed to equalize the header length of BMW OEM Euro or US exhaust manifolds! Fits ONLY E46 M3 (does not fit Z4M)
- 16.75 lbs.
- Custom built resonators, 9.5" x 4" OD
- Full 2.5" diameter tubing! We are the ONLY company to offer this diameter tubing! All others have reduced their size to fit.
- Custom pie-cut radius bends to maximize enhanced bend radii.
- Allows for use of all OEM factory underpanels! No cutting or modification to the panels required!
- Includes Rogue Engineering HD transmission brace (a $195 value!)
- This item does NOT eliminate catalytic converters on US vehicles!
FITMENT ISSUE!
For those with AA exhaust header manifolds, there is a confirmed fitment issue! The headers terminate too HIGH up against the chassis making it harder to fit these (and our other 2.5" diameter Section 1 RASP pipe).
