I have a catless invidia uppipe for igw style turbos. I bought it thinking the 08+ had cats but apparently not? Never used. Comes with turbo studs.
Probably 150 being that it's still new, no gaskets, just studs. I did a little research and obviously there are huge gains for oem catted replacements, but I also found oem catless flows less than aftermarket catless, like 30cfm. Basically, if you didn't want to buy it, I'm not going to be devastated, but the offer is only to you now that I might end up using it.
Yeah sorry I wasn't much help. I didn't really think it was of any use to me when I first posted. As for the price, I just went off MAPs website, since I've been boned on fake/imposter parts from other suppliers, mostly for my non-subaru project. Best of luck to you!
