Took off, Hiboost 2.5in Dp and stock cat and newly discovered burnt up 2nd
o2 wires, so I'm running with 1 o2 sensor. Running open Spipe.
I don't understand how it's louder with the Apex 3in catless on , than just open Spipe. Didn't do it for sound though, thought I had an exhaust leak, which I think I did. Car would feel like it was gonna stall when letting of the clutch to drive in 1st and now it doesn't act like it's gonna stall.
Gonna put the Apex 3in on eventually but it seems to actually run harder open s pipe than it did a long time ago when I had the Apex on, but you have to spool up the turbo in order to take off and feel anywhere near fast. I tried everything when I did have the Apex on and it wouldn't run right, ever. And the smell goes out the front so I don't smell any exhaust as opposed to a catless downpipe that extends to the front doors. Very stinky.
I need to install the ATP wastegate and It will run like it used too. I really hate to used to have almost 8psi, and now have dead on 5psi. Car sounds like a Srt-4 at the moment. Still have bad front o2 sensor.(spin)
