[Red Mustang Gt 46]

I had the aluminized...they are probably the most corrosion resistant mufflers I ever had. They also have stainless...

If your going to go with the Magnaflows, just be aware that they are not much louder than stock but have a deeper tone. The loudness increases as the stainless packing settles, this could take up to 3-4 months. You might want to look at the Magnapacks for loudness. I replaced my flows with stainless Macs, they are a good balance of sound without be overbearing.

Good luck...
