I got the mopar catback (corsa) for the 6.1 when we bought our r/t. I had to have the cat pipes expanded just a little bit so the catback would fit because srt exhaust pipes are bigger. Other than that they fit perfectly.

Yeah the SRT exhaust is 3" and R/T 2.5", You'd need to stretch out the mids, or better get the larger mids in hi flow or catless!

That tool may or may not work, Idk. Easier to just pay a good muffler shop with a hydraulic pipe machine. I think I paid 100 bucks, and didn't have to roll around under the car trying to install the catback. Well worth it to me.
