i just installed a megamax exhaust system for my 2005 honda 400ex. i was wondering what would be the best way to install the discs, and quiet core. if i should use the quiet core or not. this system came with 9 discs and i was wondering what the fewest amount of discs i could safely use. i dont want my exhaust to be overly loud and make people in my town mad/ irritated. also can i use discs before the quiet core. like put two discs then a quiet core then 7 more discs. or should i just put the QC first then the discs. any information would be most appreciated. im looking for mostly gains in the low-mid powerband.
