I was previously at Stage 1 + SF Intake and that was fun hearing the whoosh sound and hearing air getting through the intake. Decided to up my game a little more and ordered an Invidia Catted Downpipe from Fast Tuning Products. I also have a Invidia Q300, so they paired up great! Noise output is MUCH MUCH louder and deeper (maybe a placebo). Im boosting a little earlier compared to stage 1. Id say around 500 rpms sooner than before. I didnt have time to data log yet but I was able to live monitor Boost and Fine Knock just to see if I'm over boosting or if there were any leaks. Im on the standard wastegate Stage 2 + SF map with my boost at 18.4 psi. No numbers coming back on Fine Knock but Target boost is suppose to be 16.5 psi +/- 1. Am i overboosting? I tried to switch to the LWG map but im having trouble timing the "turn on ignition and press ok immediately" direction.
Other then those issues, I found the installation to be a ROYAL PITA! I love working on cars in general and would consider myself knowledgable when it comes to being a mechanic. Read a few DIY's and watched a few videos. It was simple enough, but when you actually under your car or above it, those bolts just dont budge!!!! The angles of the bolts were awkward and I had to remove the TMIC to get better leverage to some bolts.
Overall time for installation took 2 days.... I spent yesterday dealing with 1 bolt that decided to seize up on the last few threads when removing!!! Then another 6 hours today removing and putting all the pieces of the puzzle back! I took longer than any guide estimated time for time of labor lol, but i just had to make sure nothing went wrong or i was missing steps. That was probably just my ocd. Anyways, here are some pictures of the labor and parts!

The bolt that t'd me off! The other bolt came off in less than a minute with a breaker bar. I dont know why this one decided to act up.
