Well, I WILL have one here...I'm getting it installed tomorrow so I'll have a full review here then
The installation took a little longer than we all had suspected, because there was already a car on the lift at Garage SPL being worked on, so they had to do the installation on the ground. Matt (the mechanic) noted that it was hard to reach the end of the stock downpipe that attached to the cat-back from a ground install, but eventually he got it out. After getting it out, he found out that my 02 sensor was cross-threaded and wasn't sure if it got damaged or anything. He was able to put it into the new downpipe just fine though.
After the install, Alex (my buddy who works there) turned it on and wow was it loud. My cousins and I went for a test drive and immediately noticed that it REALLY smells! Oh man! Does that smell go away, or at least become not as strong later? I sure hope so. In any case, we also first noticed a really loud sucking-air sound, a lot like what a short ram intake sounds like, but coming from under the car rather than in front of the passenger's seat. Perhaps it was a leak? Not sure...hopefully someone with a cat-less downpipe can shed some light on this one.
Later on, after doing some family stuff, I finally went for a test drive with my cousin. Here's a short video of us pulling out:
It's definitely a lot louder, and it should be noted that I didn't go WOT at all in the video...probably 60% max. I had to turn my boost down since it spiked up to 1.16 bar. I also noticed that with my slushbox, it didn't shift as smooth anymore, but maybe my unichip just needs to be tuned for that. I'll be getting my unichip tuned tomorrow morning with my Blitz SUS getting put back in, so we'll see how that goes
Otherwise, the throttle response is incredible now, and the couple times I did go WOT it just kept pulling...I hit about 55 mph in a 35 by accident coming home from my cousin's house because the throttle was so much more responsive now. I'll have more to say tomorrow after my unichip is tuned
OH YEAH...and no CEL so far
