Big Gun Exhaust Evo Street Series Full System Exhaust for 14-15 Honda Grom

This review is not as glowing as the others, so I will provide the best information that I can. The Big Gun exhaust system uses some very good material in the product, however; the system cuts too many corners on the mounting. The head pipe does not have any mount on the entire span to the muffler. The stock system uses two (threaded 12mm) mounting gussets on the frame, and the Big Gun does not utilize even one of them. The muffler also has insufficient mounting since it only has one mount (vs. the stock muffler uses two). So the system relies on the flange on the cylinder head and one bolt on the muffler for support. The clamp on the pipe / muffler joint is not sufficient for the lack of mounting support.Interaction with the product support at Big Gun did not produce anything substantial. I am not impressed.Overall I would grade this product a C- (below average).

this exhaust is great, I put it on my Honda grom and now it sounds so good, gets the attention of other drivers on the road. not to mention how it looks fantastic.

VERY SATISFIED
