So I installed this a while ago but have not had any time to post the video and pics, been having way to much fun with it So here is the video and the pics of the install and on the car. P.S. sorry for the video my friend did it that way.
Looks nice! My friend had the M2 on his IS and he said the fitment was a little spotty. Did you experience that on the GS? How's th sound? any drone?

The only issue we had when installing it was the bolts my Exhaust guy said it was better to keep the orginals on as the bolts would have created a problem, and we would have had a problem fitting it on, so he didnt and it took him maybe 20 mins to install with no issues. There is a major drone unless I push down on the pedal the drone is there, not bad but its there. Sound is perfect.
I thought exhaust was supposed create better air flow so faster response.
Not necessarily. It can change the hp/torque curves so you may make more peak hp/torque at a higher RPM, but lose some low rpm hp/torque. Really all depends, but from my experience exhausts have given me more power at higher RPMs due to the larger pipes giving you more potential once you get up to speed at WOT. I also would gain a slightly higher overall top speed MPH. If you chip your car or tune it to the exhaust, you can rectify it sometimes.
