Product Overview
DAYTONA SR400/500 (78~08) CHROMED MEGAPHONE MUFFLER, 94500
Suitable for all SR400/500 models built between 78 ~ 08. The Daytona SR400/500 chromed slip-on reverse cone (Megaphone) muffler kit is a great replacement for the large heavy factory unit. Muffler is designed to be a no fuss solution when wanting to re-style your bike and add a nice thump. Use on Café racers, Trackers and Custom builds. The styling is versatile, so if you change your bikes style, the muffler will in most cases look great with you re modelling.
The carbie version is JMCA rated for noise regs in Japan to meet or better the 94dB noise level on standard bikes (see specs below), JMCA certification number - (1016002048). If looking to avoid an obnoxiously loud muffler that upsets your neighbors, but one that gives a nice SR "thump" and great styling, then the DAYTONA slip on will suit your needs.
A centre stand stopper is required separately (as you lose the stopper that goes with the factory muffler). The stand stops are available in our Engine /exhaust section.
The muffler can be used on the SR400 & SR500; however, the noise level will vary slightly on the 500 compared to the SR400 if your bike is tuned - (it may be louder on the 500 in some circumstances). Muffler suits fitment with standard factory head pipes and can be installed with various aftermarket headers that are suitable (if they are made to the factory pipe specs / length etc.).

YouTube CLIPS BELOW:
+ First clip here below (top) shows the SR400 (carbie model) testing at DAYTONA with slip on muffler and adjustable ignition plate. This is to show the tuning process Daytona carries out. Muffler in use is the carby megaphone phone as sold on this page.
+ Second clip is the slip-on muffler SR400FI (injected) version on DAYTONA's test track. The FI version is quieter than the Carb muffler, however the FI clip below shows the slip on compared to the factory muffler, so clip is great to see the visuals.
FAQ:
Q: Can I fit this slip-on muffler with my factory head pipe?
A: Yes, this muffler fits all carbie models built between 1978 and 2008.
Q: Can I fit this slip-on muffler with aftermarket head pipes (stainless etc.)?
A: In most cases yes, as long as the aftermarket head pipe is designed to be the same factory length and has the correct head pipe to muffler joint diameter. But keep in mind the muffler is tuned with the factory head pipe, so some minor adjustments may be required depending on the size and tune of the A/M header.
Q: Can I see this muffler on the bike?
A: Yes, see the video preview tab below for the full YouTube clip.
Q: Why is this muffler different to cheap options online
A: This muffler has been developed by Daytona Japan and is fully tuned and tested on their dyno. It has internals fitted to take care of gas regs, and noise level has been kept at a sensible (legal) level. The kit is made to be a bolt on unit (so no extra fabrication needed!). The quality far exceeds cheap mufflers, and you will enjoy long life usage from this product.
Q: The muffler is chromed; will it get rust?
A: All chromed products change over time, especially if you live or park near the salt air / water. Clean regularly and wipe down with cleaner to keep it shiny.
