<\/a><\/p>\nWhile I’m waiting for the stuff to arrive today, I received this. Chambered Exhaust “Powerstick”.<\/p>\n
This will be the last ditch effort to make a good sounding exhaust for a single pipe setup.<\/p>\n
According to the research I’ve done high pitched noise is not a pressure wave that can be canceled out with a “J-pipe”. The high pitched sounds travel along the walls of the pipe bouncing back and forth.<\/p>\n
While the Y-pipe may cause a lot of this noise, getting rid of it has been unsuccessful thus far.<\/p>\n
What I have done with my exhaust so far:
\n-Installed larger Borla XR1 muffler (No Cat) – ok but no CAT really makes it raspy (buzz). The muffler had a turn down right after it which made the exhaust loud inside the car. Drone was a little bit of a problem too.
\n-Installed High Flow CAT- helped Rasp (I always suggest installing a CAT for 2 reasons, 1. makes the rasp less and 2. makes the exhaust smell a little better)
\n-Cut out Pacesetter Y-pipe and welded in Magnaflow y-pipe – Made little to no difference to sound apart from the new y-pipe was thinner material so the sound resonates a little from the pipes.
\n-Cut off the turn down and welded in a factory like turn back – This was the biggest improvement to the sound from the driver seat. No rasp (buzz) heard and the drone was completely gone. Turn downs or “dumps” are bad for drone.<\/p>\n
I still have the raspy buzz outside the car, as heard in recent posts. My hopes is this Powerstick does the trick. If so people can save a penny or 2 from a TD setup and Just add a 60-80$ powerstick. We shall see.<\/p>\n
The reason I went with the Louvered design is because a Borla muffler is basically a perforated pipe with sound deadening material in the muffler. so since it doesn’t kill the high pitched noise i don’t see why another would. According to the spec, the only downside to this is 5% less flow, which in this model should be zero because the louvers are not less than the 2.25 pipe on the inside.<\/p>\n
