looking for input

Ok, I have a 99 f150 5.4L 4x4. I am looking into a Flowmaster super 40 or 44 si/do. I like the deep rumble sound. also at this time if found 2 broken studs for my manifold so what I was thinking was a pair of Pacesetter LT headers. Also what about eliminating the rear cats I dont want Kackle from the truck that sound is for my Harley.
What I am looking for in responce is ya all's opinion on the mufflers? What about the Pacesetters, do they last, built well? What about eliminating the rear cats. will I tun into any problems with that?

PS I live in Illinois just to let you know what type of weather I will be putting up with. I also have a can tuner (superchips)
thanks-

If you dont want a crackle, you shouldn't go with LTs and Flowmasters, but if you X pipe it the X will eliminate crackle except at wide open revs.

as for weather, I wouldn't bother with Flowmasters unless you buy the t-409 stainless models, they're available in 50 series, 40 series delta, and Super 44. I would also go with the long lasting Dynatechs but most people report decent life from the Pacesetters.

Definitely wont be running your front cats with the LTs, the LTs collectors are too long. Go with a set of Magnaflow 94106 or 94136 cats.

flowmaster wont give you that deep rumble. look into magnaflows, borlas, or dynomax bullets for that.

Flowmasters don't have a deep rumble? Never heard that before. Flowmasters and LTs sound amazing. Deep, and throaty!

I vote original 40 FLowmasters! 44s will be too raspy with LTs.

They are deep, just not as deep as the mufflers listed by Mig. Flowmasters big open chambers give a deep hollow grunt where as the other 3 mufflers are rockwool packed, and ceramic inside which absorb drone sound and give a deep rich & clear sound.

Even my magnapacks are deeper than my old 40 series with a much cleaner tone and sound.

I'll try to get some fly by's and acceleration vids later in the week.

I may be going to the dyno tomorrow, if so, I'll video tape that.

He did the runs in 3rd but on this one it downshifts to 2nd when he gunned it. You can see how hard the thing shifts between 2-3. I thought the bed was gonna fall off!
