hey ya'll i am planning on hacking off my stock muffler tommorow and installing a 40 series flowmaster with turndowns before my rear axle. i have seen a few people complaining about interior drone and i wanna know how bad it is going to be with a 5.4L. If anyone could help that would be wonderful.

 

Flowmaster is a known droning system, a dumped Flowmaster is gonan be pretty harsh. Save for the extra money and have tailpipes and tips installed.

After you do a turn down you will have to keep cleaning under the body because it will overtime rust the underside of the bed out, and ofcoarse blacken it with exhaust fume.

 

ive got the exact setup youre talking about

and yeah it drones, but its not all that bad...although i have the 4.2

IMO its gonna sound badA from the outside atleast

but darren is right about the rust and black stuff under the bed...i clean the crap outta mine about once every two months tho

 

what about some other type of muffler like borla or something?

 

if you dump it its most likely still gonna drone

but maybe not as much if you go with another brand..not real sure

 

thanks blackedout, how bad is your drone? like you havta blast music to cover it?

 

My factory radio was NOT loud enough to cover up the drone of my dumped setup, it is a headache anytime driving. If you are wanting to save money, run it out lightning style.

 

no i can tolerate it with no music on at all actually
i honestly dont mind
altough your V8 might be much louder

and my two 12's can cover up about any noise i want haha

 

My 4.6 will be alot deeper and not as raspy and high as yours, so it will be more annoying than mine was

 

yea but if i do it lightning style wont it look a little, ummm, crappy? not to offend anyone i just have never seen it done on a 4x4,

 

look at mine, it's 4x4 lightning style, vids in sig.

 

ok joshmac you changed my mind on side exit, what size tips are those and what angle cut are they?

 

The magnaflow setup has 3.5" tips, and the straight piped had 4" tips, they were both 45 degree. The 4" were 12" long and the new 3.5" are 18" long.

 

man i appreciate your help, i am almost positive that is what i am gettin tommorow now

 

get compliments on it quite a bit. i do prefer the tips out like that, look more aggressive than having them rolled on their side. 2.5"x3.5"x18" Silverline tips
