I recently finished installing American Racing Headers w/ high flow cats and Corsa catback on my 2015 SRT.

Overall the install wasn't too bad. I did it on jackstands in my garage. The driver side was very easy. I removed the valve cover and had tons of clearance! I also installed the fuse box cover from Woodhouse.
The passenger side was a little more of a struggle. I did not lift the motor or remove the valve cover. I probably should have to help remove the stock manifold, but too late now The ARH slipped in with no issues.

Connecting the lower pipes was a struggle by myself. It would help if someone was able to hold it up from underneath whole installing bolts from the top but I got it done. I made a "special tool" to help tighten all 6 bolts. I got a 12pt 3/8 wrench and used a hammer to bend it at an angle. With that I was able to reach all the bolts not accessible with the ratchet and socket.

Here is a short video and low RPM revs. I'll get a driving video soon. Ive had lots of cars with headers/no cats (Camaros, Mustangs, etc) but this is LOUD! At WOT the Corsa is very raspy. I'm wondering if I should have gone with the ARH catback. And may eventually swap to it, but I'm happy for now.
