Has anyone installed just an X-pipe for the Cali T? If so, how significant was the improvement? I originally planned to get some catback valved exhaust (Capistro) for my T, but someone told me that the improvement wouldn't be as significant without an X-pipe or sport cats added on also. I ordered an X-pipe (Larini) and will see if that's enough to improve the sound or need to add catback exhausts also.
Not a Cali-T, but I installed Capristo sport-cats, X-pipe, & a tune on my 2011 Cali. Left the original rear mufflers on (pinned open). Really woke up the sound. More of an F1 sound under acceleration & great pops/burbles when down shifting. I recommend.
No extra power,but a higher pitched (more like normally aspirated) sound is what you get from an x-pipe (I have Kline on a Portofino).
