With my 2011, I was complemented on my SW headerback constantly. It sounded exotic like a high revving super car. Once I went turbo, the SW exhaust caused too much backpressure so we had to put cutouts in, and eventually it was switched to Magnaflow exhaust which was not restrictive like the SW.
12.5 compression, so that means no boost ever right? This sucks for those whom get bored easily. I know this wasn't the purpose of the car, but it is always nice to know you can up the ante if you want to lol
I had this header-back exhaust on my 11 and it was the best sounding exhaust I have ever heard. Sounded like a high revving supercar.
When I went with the TT, the catback caused a LOT of backpressure forcing me to change it out. Are the diameters of the exhaust exactly the same as the 2011...
