Puch Exhausts

This is a little summary of Puch Maxi pipes with some basic info about what they are made for and how they perform.


"Made for" reflects to the cylinder size these exhausts work best on.

"Sound" reflects to the sound the muffler makes. Please keep in mind that sound is also dependant on the type of cylinder, air filter & carburettor you use.

"Rev-range" reflects to the RPM range this exhaust is useable for. IE. you have a Metrakit with a low to mid rev-range, and you want a Simonini that has a pretty high till very high rev-range, you'll know that isn't going to be the best combination.

"Powerband" reflects to the pull the exhaust creates and where it happens.

"Quality" reflects to lifetime, finish and other aspects that have to do with the quality of the material.

Technigas Next

TecnigasNext.jpg

Made for: 50cc till 70cc

Sound: Very quiet, quieter on the bottom than tecno estoril, but gets louder up top

Rev-range: Low to medium- high (3000-7000 stock, 4000-8000 with kit)

Powerband: Hits hard early and pulls to a fat midrange, shuts down like tecno estoril but a bit later

Quality: Very very good, probably the sturdiest of the non-american made pipes

Comments: Somewhat expensive for the performance, but will probably last the life of the bike. Great for mildly tuned stock cylinders or conservative kits, a good pipe to pair with a 60cc airsal or alukit reed for a nice torquey around-town 45mph bike. The header is long and narrow so the power comes on late, but it is well designed for a broad subtle curve, and doesn't have the restrictor that causes the estoril to shut down. If you want something cheaper, get an estoril, if you want something faster get an estoril and derestrict it. If your mom is riding the bike to commute spend the money on the Technigas

Technigas Twin

TecnigasTwin.jpg

Made for: 50cc till 70cc

Sound: Unknown

Rev-range: Pretty high

Powerband: Mid-revs till pretty high

Quality: Good

Note: To fit, you must remove the pedals and add a mounting point on the right side.


Tecno Boss

Pipe1.jpg

Made for: 50-70cc

Sound: Poppy

Rev-range: High on a stock cylinder, mid to high on a kit

Powerband: Comes on very gradually, for a stock cylinder with mild porting it will provide enough boost to let your cylinder keep pulling higher, with a kit you will feel a more noticeable gain from 8000 up. Not as powerful as a 'big pipe' so it wont catapult you into demonic super revs, but a nice big header wont hold you back.

Quality: good, baffle is welded into the rest of the pipe so it doesn't have the same drawbacks as bullet/biturbo like pipes.

Notes: looks stock, considered by many the best of the lower price bracket puch pipes. can be paired with almost every cylinder for a modest increase with limited drawbacks. Can result in a moderate loss of torque on 50cc. Header extends into chamber at weld about 2.5 inches, so for maximum performance remove the offending chunk of pipe and weld it back together.

Tecno Hunter

TecnoEstoril.jpg

Made for: 50cc till 70cc

Sound: Good

Rev-range: Mid-revs till pretty high
