I'm a flowmaster man myself... Came with the D.

 

haha. its a nice exhaust. ive had it for 2 years but i feel the need to change it for some reason lol

 

Well I've got two kids and they both got used to the exhaust when they were small, still small! LOL! Anyway, they're used to it now. LOL! I'm thinking of returning to OEM but it costs too much! LOL!

 

ha the oem muffler is like 5 times the size of the flowmaster. big A$$ metal lunch box

 

That's why I'm gonna stick with the FM! LOL!

 

lol good choice.

 

I'll be a good Samaritan and give you my OEM muffler! All i want in return is your FM.... sounds like a good trade to me!

 

lmao^^

 

ok so i got my new muffler installed sounds nice i gotta break it in now! question though.

how many cats does the 4.7l engine have? one on each downpipe and thats it? or are there 2 pre cats and then a main cat in the middle of the pipe before the muffler?

I asked the dude how much of a difference it would make if i took off the resonator and he said i dont have a resonator but that that lump in the pipe was the main cat.

?

 

and bolra xr-1 race muffler is pretty much a glass pack. there are no chambers or anything
