Muffler Suggestions for 150 with Headers

Habbi98 · #1 Thu, September 29th, 2011, 05:48 PM

I have an 07 F-150 5.4L with a set of S.Steel OBX Racing Headers & Hi-Flow cats with an Xlerator Muffler on it. The Exhaust Pipe is 3" and with the Headers I am getting an awful sounding Hi Pitch Drone from the exhaust in the 1800-2500RPM range. Does anyone have a suggestion for a replacement Muffler that is economically priced. I have checked on MagnaFlow and they are too expensive. I am considering a Thrush Turbo, but have not heard them in the 5.4L before, has anyone heard what they sound like?

The best advice I can give you is to try YouTube. I had a flowmaster 40 that I swapped out for my old stock muffler.

I've tried the youtube option and could not find any good sound clips of anything with headers. I am contemplating going back to a stock muffler if i cannot find anything as this drone is extremely irritating in that rpm range and i will be pulling an RV almost 500mi.le.s with it. The current muffler sounds great at idle or WOT, it's just the mud range rpm's where it is an issue

Search for wickednicky.....they've got borlas for 89 ea........a pair of these might help...

Also look at performance peddler.....they've got good deals also....

Oval bodies and longer length mufflers decrease drone.....
