HEy long time no talk/write.

but yeah i am wondering how come no one makes a 3' downpipe and exhaust for 2002 audi A4, also does any one notice a big deffer when the bolt the down pipe and exhuast on to this car? if so what would be the better company to go with?

 

3" is kinda big, unless you plan on a t28 upgrade. 2.5"-2.75" will be fine. I don't know why anyone doesn't make one but im sure its because the B5 is better and more people tune and fix up them. The reason why 3" is to big is you will loose back pressure and won't get much torque gains. I have a full turbo back exhaust system. Im frontrak and they really dont sell many exhaust systems with a DP. But i have 2.5" milltek catback, 2.5" techtonics tuning DP, a labree test pipe, removed the mid muffler and replaced it with straight piping. Out of all the exhaust parts i have installed, the testpipe "felt like" it gave me the most HP, then the DP, and then the catback. For downpipes, i would deffiantely reccomend techtonics tuning, and tantrumwerks.

 

Hey, i own a frontrak as well, and i am looking at doing a custom exhaust...where did you get your down pipe...im getting a atp testpipe....so, trailboss, could you hook up a link?
