NEUSPEED's T-304 stainless steel sport exhausts for Audi A4 1.8T has a low,
growling sound. The diameter exhaust system features smooth mandrel bends, leak-free
TIG welds, and mirror polished end mufflers and tips. You’ll get increased
horsepower and torque for a strong, smooth pull throughout the powerband.
Flanged joints allow for easy installation and perfect alignment. It has
2.5" tubing and Dual slash-cut tips. It is a complete exhaust system,
including downpipe, extends all the way from the catalytic converter to the back
of the car.
I had this installed by my buddy Thonnie at Midas.
