I have a 2010 Maxima and wanted to know that on a cheap budget what kind I can add to it with a cold air intake, either a cat back muffler system, or complete exhaust system. I want a real deep deep throaty sound out of it I listned to the greedy and flowmaster but so far flowmaster seems deeper. The Borla system has to much of of tingy sound out of it. Any help would be greatly appreciated.

 

On a cheap budget you can just remove the mufflers. I ran mine this way for about a year and definitely liked the deep growl. My $.02

changing the resonator would give you a lot of sound options.

 

you can go thru all the old threads to find out any information that you want on this forum. find things like BOP's, intake manifold spacers, intake, exhaust, y-pipe, and true cold air intakes. there is a search tab up in the middle of the screen. Read thru some old threads for ideas!
