Does anyone happen to have them? I assume they're roughly the same size on the 420A and 4G63-equipped cars, but I want to be sure. I have a 420A eclipse I'm turbocharging soon (collecting parts now). Getting an N1 catback on this week and I'd like to go ahead and do a high-flow cat, but it needs to be able to bolt up the stock "downpipe" for now since I'll be fabricating that after the turbo is installed.

Everything I've found on the net (replacement parts) say OEM fit and "16.5-18.5 length" 2 inches is quite a discrepancy, I'd like to clear it up without crawling under the car, preferably.
