Hi, I'm new to exhaust, and i have a 98 f150 4.6 and i wanna change my factory muffler to a flowmaster super 40 or something, how do i exactly change it, like what are the steps?

 

if you can weld cut off the stock muffler and replace with new muffler. if you cant weld buy the muffler and take it to a shop and have them do it. if you want flowmaster get the super 44 not the 40.

 

exactly

the only steps it takes is going to the muffler shop and they will cut off the factory one and weld on the new muffler (super 44 i would suggest) and run tips or turndowns whichever you prefer

 

Ok, I'll go with the super 44, and how much will that cost me if i buy the muffler? and what do you mean run tips or turndowns?

 

and my friend told me it justs bolts on.

 

Cat-backs bolt on, and universal fit mufflers come pre-flanged to slip-fit over the OEM pipe, and you can clamp it, but then you will need to hang it or mate it to the tailpipe.

A Super 44 is $79.95 for all inlet/outlet sizes and configurations.

Tailpipes & tips is the exhaust having tailpipes, and custom tips mounted, turn downs are the tailpipes stopping 6"s after the muffler and angled down for a no tailpipe look.

Figure out if you want a dual outlet system or single also. Dual looks better and sounds a bit better.

Buy a muffler, and go to a shop, and ask them to install it. And if you buy tips, take them too ofcoarse.

 

now what about the pipe that goes up and over the axle? do i have them bend new pipe for that or what?

 

Yes the exhaust shop will bent any necessary piping.

 

Ok, well i would like to get dual exhaust, but I don't think i can afford it, I'm trying to keep it the cheapest possible. so do i just buy the muffler and take it to the shop and they will put it on and thats it

 

yep. its that simple

 

alright thanks, and if i really wanted too, in the furture, i can always get a y pipe and have duals comming out the back right?

 

you can, but i wouldnt advise that, thats about the worst thing you can do

 

alright, well for now while i'm still in school i'll just stick with the single, but maybe when i graduate i'll do a cat back or true duals.
