search youtube for milltek exhausts. thats what i have and love it. it gives you that non-obtrusive low growl. it doesnt wake the house up when i pull in late at night, but you can hear the power at 5krpms with full boost. costs a little bit more, but its worth it. get the non resonated one. theres not much of a sound difference but the pedal response is alot quicker without the restriction of the second resonator. its cheaper by like $100 non-resonated too.

 

+1 for milltek. Pricey though. If/when I do it on the 97, I will do a custom magnaflow unless there is an insane deal on Borla.

 

what is the magnaflow #'s to look for? like what stuff is the best to get? catback btw

 

It's all in the A4 newbie guide sticky.

 

when josh had his a4 before he got the S4, he had a magnaflow on it. hes got a video with a drive by. it sounds pretty good. im still thinking about either magnaflow or borla.. either way im spending the same price, just borla had the DP already instead of me having to buy one then get the magnaflow done

heres josh's video
