I SECOND THE POSITIVE EXPERIENCE I HAD WITH GRAND MUFFLER.THEY DID A GREAT JOB ON MY 99 4.2 F150. WHEN I GET SOME MONEY IM GOING TO GET MY SCREW DUALED OUT CAN ANYONE SUGGEST A NICE SOUNDING NOT TOO LOUD FLOWMASTER.

 

shawnp, I had a Flowmaster 70 series installed Friday with dual in & dual out with 2.25 pipes out to the bumper on both sides of the hitch with Stainless Steel oval shaped tips(no big Bubba angle cut chrome tips. I have not done any mileage comparisons yet, But it does feel pretty good off the line and has a nice quiet mellow tone (almost to quiet) it is somewhat noticable in the cab but no where near the drone my 95 Tahoe had (FM 40 SI DO). A louder exhaust sounds real good for about a month, once the newness wears off it starts becoming annoying. My SCrew is the best riding, most Quiet veichle I ever owned, it took me a long time to make this decision. So far I am glad I did. The sound somewhat reminds me of a toned down 5.0 mustang.

 

THANKS FOR THE INPUT I WANT TO PUT A FLOWMASTER ON THATS NOT TOO LOUD YOUR DESCRIPTION OF THE 70 MIGHT BE THE TICKET IM THINKING OF 2 BENT TAIL PIPE (STOCK POSITION OF THE TAIL PIPE NOW)
