Read a lot of posts and listened to alot of clips...what are your recommendations for a tad bit deeper sound than stock. I like the deep throaty sound but not the high pitch race car on the street sound. I already have a 1/4mile money pit machine in the next garage bay just for racing. What can I get by to achieve this sound? Just resonators, just muffler or whole cat back system. But from what I noticed most of the cat back systems give you that louder higher frequency sound. Again I want to get to a richer deeper sound than the awefull tone of the stock system. It might sound goofy to say I am looking for a deeper sound than stock but not to much higher frequency louder if you can kind of understand what I am trying to say...thanks in advance to all those who respond.
