Yes, you should get this pipe!

But make sure to get a UNI Filter shortly after and don't forget to Re-Jet to a bigger size.

I'd say the muffler itself gives you a slight increase in top end power. If I remember correctly, my Super 8 would top out at 54mph on the GPS before the Two Bros. muffler and 57mph after the muffler installation. I didn't have to re-jet the carb after installing the muffler BUT I did re-jet from the factory 103 size to a 110 size main jet long before I installed the 2 Bros Racing muffler. My first re-jet had nothing to do with performance though. I re-jetted the carb because my Super 8 would bog down big time when the engine was cold. It ran great when the engine was all warmed up but I hated waiting for it to warm up so that's why I re-jetted.
I installed the UNI Filter about 2 weeks after installing the muffler and I was able to hit 60mph on the GPS for a brief second the other day. I did have to re-jet after the installing the UNI because my Super 8 was bogging big time during full throttle. I went from a 110 main jet to a 125! I was so surprised that I had to go up 15 sizes to reach the correct jet and I was a little pissed since I had bought a 112, 115 and 118 size jet to try and fine tune the carb but it was just a waste of $25 bucks since I used a 125 that I had laying around.
Also, these speeds were achieved on flat ground.

I'm confused... Petrol, you have a 150cc, right?... I can hit 60mph on the GPS with my untouched, all-stock Super 8 125cc... Is it maybe because you weigh more? I'm 5 foot 6.. 170lbs....

I've heard of other's who's Super 8s could get up to 60mph but for some reason, mine is slow.
Before the mods, I could barely get up to 50mph.

I'm 6' 0" 230lbs and my new Super8 150 did 51MPH GPS in a crosswind and 56 MPH GPS with a pretty good tailwind (spingtime in the midwest) the other day. A little slower than I had been sold on. Only have 260 miles on it so I don't want to push it too much. I must say I'm a little disappointed as I will be using this as a daily driver at some point and I will be on the highway (55MPH) going to work. Feel free to tell me I'm fat and that's all I should expect. Hearing others speeds I would like to get to 60MPH GPS just so I'm not holding it WOT for the 8 miles of highway on my trip to work (or it that a non concern).
