Ok, i love my LHS, and i plan to upgrade and improve it to my liking. my question is is there any cheap easy ways to make it sound nicer and louder. like a step by step guide or a referal to a big branch company that will do it. thank you!

 

Remove the rear rez and replace it with a straight pipe with duel tips.

did this on my cord ...very happy plus 1 mpg.

Also add a filter cone where the air box is.

I also did the same but left the rez and took out the suitcase, wasn't as nice as the rez delete.
