I just ordered the tune and exhaust from rawtek yesterday, same with the dsg tune. Im told, and judging by all the numbers for power and shift enhancements, the car will rip, aboit as fast as an R i am going to guess! Imagine that. The rawtek kit is not a straight pipe. It is a downpipe, mid pipe, low pressure egr delete, dpf delete, hi flow cat, resonator and tips in 2.75" ss mandrel bent pipe. It is a complete and comprehensive SYSTEM.
As for the tune and the downpipe, when the twin gets installed, both these items will need to be replaced, at that time i will probably sell them. Its the price you pay to pioneer a project like this. I am really grateful that these product exist, otherwise im not even sure "i" could pull it off. I will have all this stuff installed, and pics of the battery relocate in a month or so. One of the other reasons this is going to take a while is when im done, you will think the factory produced it.
