Just installed Delta Force II 50 series Flowmaster cat back system on my car. Midpipe is an off road X pipe (mac). Car is WAY to loud for my liking. I have researched several styles and makes. I have gone to mustangexhaust.com and listened to everything. This still does not tell me about inerior drone at 2000-2500 RPM (normal driving). Could anyone please give this old guy some direction? I am trying to get a tone similar to the exhaust on the new Mach-1 Mustangs, maybe a touch more aggressive. I appreciate your input or ideas. Thank you.

cat back flowmaster exhaust - argh!

 

A catted X or H pipe should definitely quite it down a bit.
