Yeah doesn't hurt to check. They could have snipped the zip tie before installing it and simply placed the DP down to roughly and it could have popped out.
I can't recall if it was already mentioned in this thread but did you make sure the gasket was installed in between the DP and turbo housing?? A lot of people miss it because it sits inside the DP flange.
Literally just because it's HKS
I personally think the 3D Maxpider mats are ugly, as are pretty much most all weather mats.
I already have Weathertechs for the winter time. I got these because I like HKS and prefer nice plush carpet floormats for the other 3 seasons.
Anywhere from like 1800 - 2500 rpm under any sort of load the exhaust would boom inside the cabin. At first I was able to deal with it, but it got to me over time. I experienced this with both my stock DP and my AA catted DP. It wasn't like Honda straight piped fart can levels of brain rattling...
I had 2 of their clutches back in the day on my Neon SRT-4. Both shit the bed in under a year. Went with ACT after that and had zero issues. That clutch was still in the car going strong years later when I sold the car.
Moral of the story: I will never buy another clutchmasters clutch again.
