Here is short clip of my exhaust. Mac Y-Pipe set up.

mac has a nice idle, but I prefer my Spintech over all...they rev real nice and sound great at idle, and it's the cheapest side exhaust you'll find...

 

i agree, spintech is definately a nice sounding exhaust. but for how cheap $ the mac is, it is definately a nice sound and i am happy with it.

i will need to get a better clip when it isn't windy, and also do a drive by.
