All,

I have Long tube headers, no cats, no resonator and 63 mufflers. I love the sound at full throttle but I want to "tighten" the note up a little as it sounds a little blat blat under mild acceleration (I'm not really sure how to make it sound on a keyboard). I'm trying to make it sound more like the video below...

 

Do you have an x pipe or h pipe?

 

I have a 3" X-pipe. I forgot to mention that, sorry.
