I just purchased the magnaflow muffler 14385 it is a dual in dual out 1 1/4'' muffler. Im just trying to make sure I made the right decision before I take it to the shop. Would the 14386 2 1/2'' be a better choice, I could always return it.

Thanks
Will

well, if you got a DI-DO 1.25" muffler, i'd most definitely take it back... :eek:

now on the other hand, if it's 2.25" DI-DO :D , you should be fine, assuming you don't have a whole lot of mods and aren't making a lot of power....it will actually probably be better, as you won't lose as much back pressure and end up losing low end torque.

but i see that you did go with the stainless steel with the built-in X-Pipe, which is (IMO) a better way to go than aluminized...and if you can afford it, i'd go all stainless, tubing and all

one thing i've thought about doing is getting the 2.5" DI-DO and going 2.5" from the headers to the muffler (mid-mounted), then reducing it down to 2.25" after the muffler for mild mods, then later when i make more power, all i gotta do is have them cut off the reducers and weld up some 2.5" tubing the rest of the way back. that way, i won't have to spend as much money to go 2.5" all the way back later on.

anyone know if that is a feasible scenario?

It is a 2.25" DI-DO. What diameter are the stock pipes from the engine to the headers? If I have then widened will they still work with my stock cats?

What does everyone else think about this? Should I keep the muffler I have?

yeah, that seems cool
are you replacing the whole exhaust or just the resonator?
if replacing the whole exhaust go with that one, if not go with a muffler that has 2.25 inner/outlet

I am replacing the whole system after the 2 cats. I was just worried that 2.5 was a little big. I plan on doing some bigger mods in the future but realistically they could come in a year or two.
