The 18" Magnaflow is a glasspack, it's just oval. All the Mufflex systems are made with Magnaflow oval glasspack mufflers. The mufflex system costs $100 MORE than buying a muffler and welding it in properly. Food for thought. The Magnaflows run $150ish on price. The average guy on here pays 40-60 bucks to have it welded on in about 30-40 minutes. I highly suggest you have it welded in. The Mufflex systems are hit or miss. Some people fight leaks, some people have no problems.
I don't have a sound clip but my 18" Jones Maxflow is built just like the Magnaflows, it's made of T409 with very nice welds and only costs 67 bucks shipped from our forum vendor BSM Exhaust works. It is very deep sounding, exhaust. Pretty loud when you romp on it, and when you are not the neighbors can sleep soundly.. At idle it sounds like a 400hp Hemi should.
