metragas GIANT MUFFLER RACING pipe - derbi or hacker special!
derbi variant metragas GIANT MUFFLER RACING pipe

alternate reality price $79.99



this is not yer mama's muffler racing! giant 30mm header, biggest ever seen on a moped pipe! for derbi flatreed variant by metrakit by technigas very solid quality construction, identical to the original mk version!

mounts on the right side!

this will not bolt on to a piston port or pyramid reed without welding a lil bracket...hobbit dudes go very fast with this pipe i hear...hack n weld n enjoi these MIGHT come with a technigas decal (not applied)

no "muffler racing" comic sans sticker :( sry. they also might not come with any stickers.

**there are some scratches and some light surface rust on these pipes! nothing crazy bad. they've been shipped thousands of miles across the world in a box with no packing. such is life. no whining!**

5 of 5 very very fast pipe April 29, 2021
taco eater : william caldwell from san francisco, CA United States  
do not let the biturbo esque chamber fool you...this pipe hauls ass on flat reed!! on par with the blue baffle.

this pipe plus a 15mm sha and some reeds got my sle-x up into the mid 50s with the stock cylinder. amazing!!

the flange is kinda annoyingly large BUT the pipe is cheap so ya kinda just gotta deal with it.

5 of 5 perfect for the DS50 October 2, 2016
taco eater : parker bowab from new york, NY United States  
I purchased the turbo pipe that was designed for the DS50, and quickly trashed it for this guy. Just buy it, dummy
Bolts up without any modification. Did NOT come with anything extra. No gasket, hardware, or (dumb) sticker

The angle of the stock mount on this pipe doesn't match the motor. After ripping this pipe for a few weeks, and bottoming out/exhaust leaking constantly I had to resort to hack and weld. Def cut off the stupid loose flange and shorten the header by an inch. Weld it all back together and make a new mount. You lose a little performance—but still infinitely better than the other pipes designed for the DS

5 of 5 Unleash the Revolution. February 13, 2016
taco eater : Matt Wagner from Dublin, OH United States  
Really great quality for the price. HUGE header. Comes with sticker, new bolts and a quality gasket. Needed a small metal plate for it to bolt up , as the rear bracket didn't match up. Great takeoff with a 16 SHA. Really hits the pipe around 40. Hitting 52 at the top end.p
