On this page you’ll find a full review of the Homoet P4 exhaust covering both the plus points as well as the minus points. A special thanks to Martijn Klerks who took the time to share his experiences with us.

Red Puch Maxi With Homoet P4 Exhaust


The sound of the is awesome. It’s low rumbly and has a nice growl. When running idle and also a bit into the rev range it’s very quiet. Much quieter than a Tecno stock looking exhaust. If you want to hear the sound yourself, on the bottom of this page you can find a high quality sound check.


The powerband is a bit of a hard one. The p4 is sold as an exhaust for 50cc and 70cc engine’s but hitting the powerband with a 50cc has proven difficult thus far, but once it hits it’s awesome, it’s very top end happy.

The combination of the Homoet P4 and a good engine adjustment results in a lot of RPM’s! For example, the setup of Martijn is : 50cc Airsal (fast), 12mm Bing, 13-45 gear ratio, topspeed 55km/h. At WOT (wide Open Throttle) he gets 9237 RPM.

Quality wise it’s a bit of a toss up. The actual metal is nice and thick. The welds look clean. The packing is nicely done. The welds around the flange are a bit too thick so that might give a little bit of trouble during the mounting process.

The paint looks nice at first, however the paint on the exhaust manifold starts melting off pretty fast. The quality of the paint is not of the highest unfortunately.

Word of advice mounting with an Airsal cylinder (50cc) can be somehow difficult. You might need to make a bracket because the exhaust was too low an too far out to reach the stock hanger.


It’s time to to plug in your headphone and listen to the sound of the exhaust. The sound of this HD video was recorded with a studio condensor microphone, pretty good stuff!

Example setups

Here you can find a few examples of setups where people used the Homoet p4.
To view all setups, go to our Puch Maxi setup page.

  • 50 cc Airsal (fast), 12mm Bing, jet 62, gearing 13/45, Standard airfilter (modified), topspeed: 55 km/h
  • 50cc Original, 14mm bing, Jet 66 , Standard Air filter (modified), topspeed: 57 km/h
  • 50cc Airsal, 15mm Bing replica, jet 80, gear ratio 13/42, Standard Air filter (modified), top speed: 60 km/h
  • 70cc Athtena AJH, 15mm Bing original, Jet 72, gearing 15/42, Standard air filter (modified), topspeed: 85km/h and running really good.


The fact that the Homoet P4 sounds so awesome, feels so premium and is quiet, totally out-weight the bad points for Martijn. It can easily be repainted, the bracket was only 2 minutes of work and the thick welds where solved easily as well. Overall Martijn is very happy with the exhaust.
