okay so i had the labree high flo cat and miltek down pipe (2 3/4inch) but i was using the stock exhaust...i was getting TERRIBLE gas mileage...so i got an amazing deal on a 3 inch straight pipe so i got it hooked up...and yeah HUGE improvement! alot less back pressure and im gettin 60 more miles to tha tank and there is a difference in the holding boost..but i sound like an SRT-4 (kind of love the garggle it has)

now before you watch this i only TEMP have a side pipe until i find a 3 inch muffler i like!! (also i was already driving the car about a half hour so its all warmed up)

i was going to do a drive by but my friend was to hooked on GTA IV to get up

 

Awesome shoes, but it's not possible to improve gas milage on A4's EVER.

 

I know that sound all to well...very loud. Drowning when your just trying to do the speed limits. Welds broke on factory punched-out cat before upstream o2. I had to coast past cops at intersections in fear of niose violations. But really cool to hear the turbo in such a raw state.

 

haha my uggs i was going to tha store mad early im not going to bother getting dressed
compared to what i was gettin (210 miles to tha tank!) im now gettin average 280 miles to tha tank so its not better mileage as more asits average againhaha

 

nah man get special purple fluid and its totally possible to get 50mpg.


and the vid sounds kinda like my car when i take off my muffler, only not as deep cuz i have a tp. the turbo spool sounds crazy tho.

 

Get one of your driving..

 

Yeah my S4 has straight pipe on it and it sounds amazing.
i just did the same thing to the A4 earlier in the week and damn it was wayyy too loud! I ended up throwing a glass pack in there which toned it down to the point where i could drive, but it still has that growl that i like.

 

yeah i just put Special purple super violet high def amber fluids all over my car made it more aerodynamic and the fluids are just flowing so natural! i get 57 miles to the PINT! its amazing!

ill get one of me doing a drive by tonight

 

You think thats loud you should hear what a 2.0GT35r sounds like with NO exhaust


3" is really over kill for anyone running anything smaller then a GT30. A 2.5-2.75" setup would be much better for the smaller turbo setups.

 

why would a 2.5" be better? after the turbo larger is better but larger also means more sound
