4" exhaust

[pmrpete]

I have had really good experiences with the couple of MBRP exhausts I installed. They're pretty easy to install. The downpipe was tricky getting it passed the tranny crossmember. I'd think you'd want the 4" Downpipe as well for better airflow??? I really like mine. I have heard good things abotu the AFE as well. I love the sound of the TB!!

pdt1081,

The 3.5 to 4.0 transition won't make any noise difference, if your truck is an XL and his is an XLT or Lariat there is more insulation in the trucks depending on the trim level and sometimes the different years have more or less too. We actually have the AFE at a lower price than the Jegs, Sumitt brands too.
