Q. DOES THE CHANGE IN SILENCER CAN AFFECT THE MILEAGE - Bullet 350?

I am 100 % sure definitely your mileage will get affected if you are looking for high beat note Exhaust (not a silencer) and its going to drain your wallet (note: there no improvement in pickup either so disappointing). only stock silencer can provide you a better mileage. If you are looking for fancy sound that sounds like dominating the road then get ready to loose some engine pulling capacity, eventually this lead to tuning your engine, here\'s the hardest part in default factory engine tuning setting with modified exhaust its a disaster in your mileage, due to drop in pulling power of engine on installing modified exhaust note you have to choose for acceleration tuning setting with modified exhaust is like burning your money that would aprox 25 kmpl. your decide up on your suitable budget.

Complete free flow are simply shit, pieces of tin cans that sore the ears badly. Muffled free flows like dolphin, Indori, shark etc are a good choice for their ablity to give good beats (thumps) at the same time soothing to ears as well. I don't rely upon a fact that changing the exhaust would Ware the engine early for exhausts job is just to curb the sound whislt the burnt gases are ejected out. I own a RE classic 2014 model and using dolphin exhaust to suit my preference, it has managed to give a mileage of +38kmpl till date with no hiccups whatsoever. Hope I addressed the query.

Yes change the silencer and get a 15 - 20 % drop in the average. Engine will be damaged . Please note that you cant get the old thump like the CI and the AVL Engines in the new UCI engine maintain stock for a long journey with your bull. If you have to change then dont go with FREE FLOW. It will damage the engine go for glasswoll exhausts.
