Here is the muffler DOPPLER model ER1 for MBK 51. This good quality exhaust has a nice look, performance at the height and a fair price. The body is a real rolled welded sheet 1.2mm chrome finish. The sheet is of good quality, volumes, shapes, counters cones ... Are well studied!
This pot works very well on an original cylinder and small 50cc kits (DOPPLER ER1, BIDALOT G1 Replica, AIRSAL T6, engine fox ...), it will not offer good performance on very sharp engines (from its sheet much too thick) nor on engines of large displacement (due to its architecture and its volume).
We would say that the diagrams adapted to this exhaust go from 178 to 185 ° maximum, with a power regime of 9000rpm maximum. This exhaust is really strong and very quiet with its absorption cartridge filled with ceramic wool. It comes with fasteners and all accessories.
Level look, it is really nice and racing, it is obviously delivered with a certificate of approval, it is clamped at the entrance of the ball joint, be careful, if you remove the input washer is no longer approved road.
To close, this exhaust has a very racing look like GIANNELLI SPORT and NINJA G2 Replica for example, it is really not noisy and very solid, it will fit with a small configuration type kit 50cc, carburation 15 to 17 , 5mm, dimmer ... However it will not follow on the 70cc and big kits 50cc has big diagrams. Really a very good pot to roll every day.
