Looking into a new exhaust on my mustang, see signature for info. Just a little indecisive at the moment. It's going to be cat-back only, and so far the ones that have my attention are the magnaflows catback muffler delete. Myself I'm not big in the performance area, so quick question. If I'm running cat-back and deleting the mufflers only will I really be losing back pressure, and if so how much will it affect the performance. Or if you have any ideas on actual mufflers that sound good, and by that I mean loud and roudy. This is my car, not the family's so they rarely ride with me in it. I don't care if I hear the sounds it my car, I just want it to sound like a beast when taking off.
