Hi. I'm new. I've googled high and low for an answer to this question with no avail. I purchased an HKS catback and want to install it, but my OEM cat is 2.25. The inlet on the exhaust is 3". Where can I find an adapter for this? I don't want to cut and weld anything because I purchased the exhaust full turbo back, which I will install when I can tune the car. For now, a catback will work fine.
What do I need? Sorry if I overlooked another thread on this subject, I couldn't find anything.
