Ya, but I don't get around on there much.
Exhaust repair
After assembling the motor I noticed, before installing my Tomei manifold, that it was cracked as the base of each runner. So I contacted Tomei just to see if they would do anything and after a few back and forth discussions and sending in a copy of my logged dyno sessions, they agreed that is should not have happened. So I figured while I wait for another one, I'm going to turn my attention to that damn Nur-Spec rattle. Just before doing my last motor, the rattle was really noticeable on my BPU SR; here is a quick video of that.

When I had the exhaust on the last engine it was less noticeable but still an annoyance. I contacted Blitz about it and they suggest I purchased an new muffler and be done with it. Considering I've already removed the resonator on this exhaust and I wasn't feeling the $400 muffler purchase, I figured I would cut it open and see what's going on inside. So this is what's inside a Blitz Nur-Spec; stuff looks beat...
Here is the place it was rattling. You can see how the welds just separated from from the perforated steel.
I also noticed that it was slightly bent up on that end as if the perforated tube was actually too long for the assembly. So after cutting it down slightly, re-welding the torn perforated material (a real bitch to TIG). I packed it full of this exhaust fiber mate packing I found online and welded it back up. I have no idea what it's going to sound like and honestly, if the rattle is gone, I'm sure it'll be a good note but we'll see when the car get back running. Surely it'll be quieter?
All TIG'd back up! Don't hate, I know its not pretty but it'll be under the car and no one will know the difference. Getting there... One part at a time. My next update I'll be back on the intercooler modifications.
