Rogue Engineering is proud to introduce our E46 M3 Rasp Pipe, the sensible way of getting rid of that nasty factory exhaust rasp. Finally, you can truly enjoy the sound of your M3 without the annoying, Honda Civic-buzzing-like rasp of the exhaust at the higher RPMs found in US-model E46 M3s. A perfect compliment to our
E46 M3 X-Pipe and
El Diablo exhaust system.
Rogue Engineering RASP Pipe V3
V3 one piece flange
High Quality Materials, Factory Like Fit
The RE straight pipe is made to fit exactly like factory. Features of the unit include:
- Fully mandrel bent tubing, no crimps or flattened areas.
- V3.0 incorporates a one-piece flange to connect to any section 2!
- New! V3 incorporates twin, custom-made, single resonators.
- 100% T-304 stainless steel, TIG welded construction.
- Dual 63.5mm pipes (stock is just 50mm). More flow!
- Weighs only 14.8 lbs. (factory weighs 14.5 lbs.)
- Will not change ground clearance
- Will not void factory warranty
- Will not affect emissions
- No permanent modifications required for installation
- Optional available hardware kit sold separately.
Version 3; Always evolving
For many years, we have been successfully selling our V1 RASP pipe for E46 M3 owners. So popular was that many others were trying out their own version. However, tuning out specific exhaust sounds is more than just "stick that resonator in there" kind of development. Sometimes it may even work, but often times, it requires tweaking for just the right sound.
Version 1 - Dual 57mm tubes (OEM is 50mm), dual resonators (3.5" OD)
Version 2 - Dual 63.5mm tubes, single muffler/resonator
Version 3 - Dual 63.5mm tubes, dual resonators (4" OD)
For Version 3.0 we went back to the dual resonators to keep the flow separate for cars with higher HP as well as cars that maintain high RPMs (like tracked cars). The dual resonator format seems to fair better than the single muffler style resonator in these cases.
As the E46 M3 approaches its 20 year anniversary (in 2021), factory OEM items like catalytic converters start to require replacement. Whereas replacement manifolds (with catalytic converters) are expensive, some have chosen the header option. By doing this, the exhaust sound instantly increases in volume and a RASP pipe is no longer as effective as before. For our track customers that attend tracks with specific dB limits, this was also a concern as their track-going vehicles were blowing pass track limits.
