I'm getting ready to pull the trigger on a pair of 1790...trying to kill the rasp my c-PE catless DPs + the "is" exhaust produce.
Question: is there way to keep the 2nd cats and install the 1790s? Normally, taking out the 2nd cats makes the exhaust louder and even less controlled...bottom line, would you want to keep your 2nd cats?
I know you directed this at CN, but i can tell you from personal experience that they will not fit unless you remove the factory cats, there is just not enough room on the E92 exhaust.
