muffler case size

4" thick....9.75" wide......13" case.

To tell you the truth I love the sound of my Flows,but I believe
there are better flowing (straight through) mufflers out there. Magnaflows ?

But for the $ the Flowmaster Org 40's are a great muffler.

sweet johnny! sounds similar in spec to the muffs im looking at (although mine are slightly thicker and longer and center in/out)..im looking at the borla's right now, but there magnaflows do flow well (although they kinda lack in the sound department imo)
