So I have a 2.5" downpipe into a 3" exhaust, no cat (well cat is there, just no "cat" And Swear To God it truly fell out by itself, questioning the integrity of the exhuast shop....) into a 2.5" muffler.....
I have owned a few 3" mufflers for a few years attached to 3" exhaust systems (basically downpipe back) but never had the time to mess with them.
Well today, I messed with it.
I grabbed the 3" APEXI muffler and exhaust, lined it up with the existing and made some SHARPIE markings. A few hours later, it was all welded up and ready to run.....
ITS SO FUCKING LOUD!!!! :devil::sadbanana::ritz::disco::banana::taco::furious::eek::rolleyes: I really am not sure what to do....
But I took it for a test drive anyway....
Wow, did I say loud?
So I got to a section of closed roadway in a school zone and got into 4th gear......
OK, I am running a 20psi max boost gauge...., so I have no idea what I am truyly runnning...
Previously I was hitting about what I think was 22psi max.......Fuel pressure was hitting 57 psi....
New 4th gear run? Fuel pressure hit 68 psi!!!!
My fuel pressure rising rate has been VERY consistant with boost levels, so I am pretty damn sure that the boost DID increase 10psi, to 30-32 psi for that run.... :eek:
I pulled over and turned the MBC DOWN!!!!!
Wagon is FASTAR than before, even for same boost levels because it hits peek boost earlier.
Hitting the track this weekend! :banana:
