ok, so i've narrowed it down to these two exhaust systems, dont tell me i should get this or that because i cant afford it so i'm gonna go with what i can afford. neuspeed vs borla.

which one is better, which one will give more power and will better handle future upgrades, which one sounds better? i know the sound question is a matter of opinion but if anyone has a sound clip of the neuspeed that would be good, thanks for the info/help.

 

borla.. just my opinion

no real facts to back that up.

 

I thought borla was more respected for audis then nuespeed was

 

Borla. Always seems fit well, good qualitity

 

I have Neuspeed and i am very satisfied. Nice rumble but not anoyingly loud.
I didn't had any fitment or noise problem. Good quality system. I cant complain

One or the other, it will be a nice upgrade to your car

 

Which exhaust would be the best for people who want to go stealth? I would like the performance gains of an aftermarket exhaust, but I don't want something too loud to attract too much attention.
The Borla exhaust looks great but I'm afraid it might be too loud. Does the Borla meet noise restrictions in each state?

 

Oh, this is something I plan to do when I chip as well, so thats what I meant by the performance gains.
Also, since the Borla is a cat-back exhaust, does it get rid of the secondary catalytic converter? My state has yearly emissions tests, so I am not sure if I want to swap it back to stock each year if I can't pass the emissions.

 

Save up for the Autospeed!

Borla! It has a nice fit & finish, it's sounds nice. The Newspeed one drones, & doesn't fit all that well, IMHO, is just cheap.

 

i do personally like the borla!

 

autospeed is loud but not that loud borla is good also for a second choice but if ur looking for stealth then borla or nuespeed or autospeed dont have that type of exhaust that will not put out a sound that everyone can hear or just u. u have a S4 man our cars are goin to b loud regardless unless ur running stock exhaust.
