I definitely want the "six cyl. rapp" sound but want to limit the harshness usually associated with glass or steel packs. An H-pipe usually dulls the RAPP and I'm afraid that the SUV 50 will do the same.
I like the "growl" 5.0 Stangs have with FM's and would like to get that with a six cyl twist, so to speak.
I already have the muffler, so price is a moot point. My plan is; 2" in, 2.25" out, 4' tailpipes ending with 3.5" x 18" bologna cut tips. Those BIG tips really give an exhaust system a deep throaty sound, something you felt more than heard.
In the late 90's my 77 Ranchero (302/Smitty's/BIG tips)used to set off every car alarm I passed going thru 6 floors of my parking garage at work. I would lug it just a little bit and BINGO. I regulary did this every morning and evening and it was a real hoot to hear 15 or 20 alarms all going at once in that garage. Security hated me, LOL. I guess that was just the kid in me. I was in my 50's then, does that tell you anything?
