Exhaust audio clips....

Iv been shopping for a full cat exhaust for my car and am having trouble finding audio clips of what they sound like on my car. Iv only been directed the the HKS site where there Hipower sounds really nice. Anyone know of any sites where i can get more audio clips of some other cat backs? Also, at the tip of the exhaust, id like it to be tucked into the bumper a little like ones seen on newer cars instead of being flush with the flat underside of the bumper. Kind of a weird question but thanks anways guys.

i dont know an exact site but there are a few with audios of the stromung exhaust, just do a google search
