Stock cat back with Helix DP
Alright, I know this has probably been posted somewhere, but after searching and searching, I'm starting a new thread, sorry guys.
I've been told different things about the Helix Catted DP mating to the stock cat back. I just ordered the Helix DP and called Scoobytuner to see if I needed an adapter to make it work with the factory cat back, they told me it would fit without problems. The Helxi states its a full 3" so I was under the impression I needed to get a flange to make it fit. If I do need it, any suggestions on sites where I can get one?
Also I've heard the UP and DP install can be a pain. I have a lift, all the tools other than an O2 socket (plenty of other sockets), and a few friends to help. I was wondering if it would be worth it to have it installed by an exhaust shop or should I just get a case of beer and install it myself.
p.s. I'll get the case of beer even if a shop installs the UP and DP, so don't let the beer influence your advice.
p.s.s. It will be Miller Lite
