I agree, not just because I have magnapacks also but because I think strait through mufflers sound the best on the S197s. When we had that run in on the highway I knew you didn't have a chambered muffler on your stang. My buddy has SLP and they also sound good. Can't wait to see what yours will sound like with the X. Seeing as you said high flow I assume your getting the X with the high flow cats ?
i went with the cat back and picked up some serious power. three in into a custom set of mufflers. go to badassfast.com and send a message to dave. i love the sound.
