If you're looking to make your car loud while saving some money, you could always get some AAM shorties and throw some test pipes in there. That'll make peoples ear bleed when you're driving by. As for me I live in Cali so I can't do that here
I had the AAM short tails and even without the test pipes they were still kinda loud(a little too loud for my taste) so I just switched the the ARK grip exhaust. My ears are in love with the sound.
Its like being able to hear a nice pair of tits. It sounds tits!
