I just bought a 1999 Ford F-150 XLT with the 5.4. I want to replace the stock exhaust with a flowmaster. I was looking at the DeltaFlow 40 Series. I want something that has a good sound outside, but dont want alot of noise on the inside. I want the big tips, whichever size that would be? I also want them coming past the tires and pointed in the direction of each corner of the rear bumper. Can you please give me some advice on if this is a good choice or what is. Thanks.

 

I have the DeltaFlow 40 on my truck....2.5 pipes with 3inch tips...I love it i have dual out the rear...go to flowmasters website, you will find loads of info there. Hope this helped.
