Just had my Kline exhaust installed with the Top Gear ECU flash. I have a 2004 X50 TT cab.
I have looked at every exhaust on the market for the past three years or so and settled on the Kline. The car is not the same. It roars under throttle and while I wont claim its faster, it sure feels like it to me. I love it! The Top Gear Tune from Sambo has also been great, no check engine lights, and a definite boost at about 4K RPM. Along with the roar of the exhaust it is fantastic. Thanks to Sam for working with me and my mechanic, Chance at Stevinson in Denver. Sam was a huge help getting the tune right and supported us through the process completely.
Sam guaranteed I would be happy or he would make it right. I am totally happy and absolutely made the right choice.
As for the Kline, it's a piece of art! Shouldn't be hidden under the car. Perfect fit, great sound!
You will not go wrong with Sam and Kline.

 

congratulations! Which exhaust did you choose? I have a 2.5 inch with 100 cell cats. Sam is awesome to deal with for sure.
