I had a local shop install my x pipe, high flows, and dido magnaflow muffler. I kept the pre cats to keep some back pressure cause im running 2.5 piping for my little 4.6. Well anyways it sounds awsome compared to my 40 series muffler. In a couple of weeks im gonna get my shortie headers installed. Ill get a video when i find my camera lol

 

Velocity, not backpressure. But congrats. Hope your low end feels alright.

 

actually its a little better in the low in. It pulls a little better then what it did. Its great.

 

Videos not the best but here they are. http://s654.photobucket.com/albums/u...efamily350.flv

Very good, very good! It has a nice stern tone to it. I like it. I am also a Flowmaster in the trash graduate. lol Removing those pre cats will actually increase your velocity, but no big E, it sound good!

 

thanks man, well reason i didnt remove them, i read heard it doesent really cause that much back pressure. But i really dk. I love the way it sounds. I tested it out and it actually spins the tires now while taking off. With flowmasters i can barley could get it to spin without wet pavements. So i think i might of got a bit more power out of it.

 

more videos
