Doesn't fit Grom Vader 125cc Boom Clone

This front muffler doesn't fit my Vader 125cc Grom Boom Clone but I really like the muffler so I ordered another muffler for it and I love it, like it Muffler sounds really loud so I put a DB killer in it and it's perfect

Pros
  • Confident
Cons
  • Everything OK

Great price and package!

The assembly is excellent, it didn't take long to install if you watch the video on YouTube. There are no instructions, but tools to pull the springs are included in the kit. The deflector is removed, be careful not to drop the screw! Sounds amazing and it's easy! Hello seller, can you send me an impact screw?

Pros
  • Stylish and modern design
Cons
  • Quick start guide

Fits perfectly! 5 minutes to install, arrived on time and sounds great! Not loud, but just right!

Perfect fit! 5 minutes to install, arrived on time and sounds great! I didn't want the exhaust to be terribly loud, but I didn't want it to sound stock either. I wanted something nice and functional! If this sounds like what you are looking for, this is perfect for you! Honda Thunder 2020

Pros
  • Trial year
Cons
  • So far so good

Very noisy for the price. Good sound

Installation was very smooth and easy. Significantly louder than stock, added a cold start video right after installation but doesn't justify it, sounds really good, might just be too loud for my taste but sounds great. I need a programmer, because when you ride a cold bike without it, it hisses a little at first, but after warming up everything is fine.

Pros
  • Ease of use
Cons
  • Secret

Some lubricant for the stain when installing.

I'll start by saying that for this money you can't go wrong. My grom is 2015 so you need to adapt the rear bracket to this exhaust. There are no instructions with the muffler and there is very little information anywhere on how to fit the back of the muffler. The 2 12mm nuts securing the upper tube to the head should be alternately tightened until the upper tube is seated on the head. For a rear mount, locate the cavity on the back of the rear kit and drill a pilot hole followed by several…

Pros
  • handy thing
Cons
  • small change

Best exhaust for the money

When I was looking for a thunder exhaust I didn't want to spend money and rob a bank. I'm a college student lol. When I saw this coupon exhaust it was only 70 with crazy taxes! No instructions were supplied but is very easy to fit and comes with all tools and an exhaust bolt. I have a 2020 Grom so I'm using 2 stock header bolts for the new exhaust, it has a loud aggressive sound with db out and is nice and quiet but louder than the stock db out exhaust. Lots of snaps and snaps too when gears…

Pros
  • Satisfied so far
Cons
  • Will write later
