Various exhaust setups I have had on my 08 and 12 ISF. Loved the stock headers+Borla+muffler delete/bazooka the most so far. Perfect blend of throaty but not much drone and very daily drivable. Still searching for something better for the spring. Listed as in video:
1-completety stock- nearly silent, only sings above 4k.
2-Borla catback-minor drone but fairly quiet. Most surprised it didn't sound like this from factory.
3-Borla catback with muffler delete-similar to RR Racing Bazooka tips. Minimal drone, almost less than Borla with mufflers, but much throatier sound. Loud enough to grab attention, but not too much.
4-PPE Unequal headers without cats and Borla catback. Sadly didn't realize till later that I had an exhaust leak. Droned but was quieter than borla with muffler delete.
5-PPE Unequal headers without cats and with Borla with RR Racing Bazooka attachment. Loud. Terrible drone. Sounds like a monster ripping it above 4k. Smile won't come off your face and multiple thumbs up a day, but taking a simple drive to the store or work is a headache. Not daily drivable and good luck with cold start with neighbors. This setup in the video was actually after I installed two small resonators that only helped tone it down maybe 10-15%. Without the resonators it was even louder..
6-PPE Unequal headers without cats and with Borla. As mentioned, I added two small resonators and it wasn't enough, so I threw the mufflers back on and now it's quiet and still some drone. Not OEM quiet, and sounds good above 3k, but I want the bark back from the 3rd option I had(Borla with mufflers off but stock headers).
Come spring time I will try something else! Goal is HKS or Joez, maybe something else. Any ideas?
