i have 5in mbrp on my its pretty loud but sounds good to me

 

Got everything installed this weekend 3-1-13. it was real easy going untell we broke one of the 2 bolts that hold the down pipe to the turbo that set us back a little. had to center punch and drill it out dang old bolts. But after that it was done! the sound is so clean is a bit loud but its a great sound. And a great rumble and the truck pulls harder and has greater throttle response. The monster 4"ta6" to 18L" tip looks really. the intake sounds like its going to get sucked clean threw, Turbo sounds great!. Thanks for the great info
