I did the BBK headers with pypes x pipe with cat delete, sct tuner, and K&N intake. I was concerned with the volume so I kept the stock mufflers. I have a GT premium convertible. It sounds great at low end and idle, has a nice classic rumble to it. At cruising altitude with the top down I can still hear the radio fine and carry a conversation. It sounds great with extra pep.
MBRP Performance on 05 F150
Installed the exhaust system on my 05 F150 5.4 CC after a much needed replacement from the stock exhaust. I had the system installed within 1 hr, took longer to removal the stock exhaust then it was to install the MBRP. The sound is right on, not over bearing in the cab and no drone on the highway. Sometimes I step on the gas when I'm cruising just to hear growl. Auto Anything as always is great. My only issue was MBRP messed my address up and I had to wait 2 extra days for FedEx to fix it.
Stainless Works Headers
Well easy to install it is not. Not because of the headers just the nature of the beast. Installed the high flow cats and performance exhaust as well. A lot of work in the driveway but well worth it. all the factory hangers points worked great with the supplied hardware. Sounds awesome and added a big kick.
