Has anyone replaced the stock muffler on a 2000 5.4 with something that will allow for "freer" flow? I am interested in replacing the stock with something that may add a small amount of performance and a little rumble to the V8.
Any suggestions/thoughts would be appreciated.
I had a Borla cat-back system along with Borla headers on my '92 Explorer and when $ gets freed up I'll go with Borla for a cat back. Remember that the bottom line for performance is that one solution just exposes another bottleneck until you've opened up your MAF orifice, throttle body, gotten rid of the OEM air filter/air box and added headers.
Be careful of following the F-150 advice to the letter. The 5.4L SD is different enough from the 5.4 that goes into the 150s and Expeditions (airbox, size of headers, size of exhaust, cooling, etc) to warrant finding a 250 that something worked well on.
I have a Dynomax 3" welded. Summit, about $50. Not as loud as a 40series flowmaster, and nice at idle with a nice rumble at start up. Not too loud not too soft, for me, when your on it. A friend of mine has to 2 1/2" x-brand turbo mufflers and "resonator" tips on his gm and I think that the dynos sound a bunch better. I've also heard the 50 series FM and IMHO the dyno's just sound better. I hear some around here and they sound too, poppy is the only word i can think of, almost like cheap glass-packs.
