My stock muffler == Shot!

[Kenny]

Beat me to it .....Went Magnaflow about a year ago. Lost at least twenty pounds in the process. You may want to consider a resonator.....that muffler is gonna "drone" a bit...a lot. Sounds nice and burbly at start up tho

Oh ya!
Go with a resonator.

If you want improved performance and mileage go with an Aero:

I have been enjoying the performance gains on my aero-turbine for nearly 4 years now.

We also offer that brand too, but to be honest they are
a little overpriced for what you get.
The Magnaflow imho is a little more affordable and works
really just as well. Their 18" version wont be too loud either.
The aero mufflers Ive heard on other local Suvs are a little
too throatie for alot folks.

my exhaust system is likely due for a replacement in the next couple of years as it looks kinda rusty, no holes yet but I'm sure it's simply a matter of time, I'm not necessarily looking for improved (more aggressive) noise, if I was only interested in that I would have kept one of my Alfa's and besides, the VX is plenty loud already
but when I am looking for a replacement exhaust system, are there tangible benefits such as performance or gas mileage, or will it all be in my head (or ears! hahahahahaha)

Generally speaking to improve on hp or mpg you
need a nice free flow muffler. Some of the best performance
mufflers are straight thru design. Ie Magnaflow and some
others. How they pack the muffler overall length of the muffler
generally determine how loud it will be.
Magnaflows are packed with stainless steel. Last longer and does
better at quieting things up then something such as the old
fiberglass packed mufflers, ie turbo mufflers etc.
I suggest something that should be the best of both worlds is
this one:

Covers all the bases and well built and cost under $100.
If quiet is a MUST, then we offer and most shops around all offer
the old school turbo style muffler with an S pattern tube inside for
flow and glass packed, avg cost about $50. The S pattern inside the muffler
flows a little better then stock, but still packed with fiberglass it will be
pretty quiet. Problem is over a few yrs time, it tends to get louder with age.
The Magnaflow wont do that due to its stainless guts.

Great! Thanks for the input Vehi-Cross-AZ!

just out of curiousity ive been wanting to replace my stock exhaust sytem but how much does the actual muffler weigh?

The new one about 8lbs
less then the OE suitcase sized muffler.
Ill be installing one on my own Vx in the next few weeks
with pics before and after and even a few vids on youtube
to be able to hear it.
Im also going to get a baseline of my mpg at the moment
stock, and then after the muffler install.
Ill even weigh both mufflers let you know the results if you want.

Put these on a customer hot rod a couple of years back. No "seat of the pants" performance gains (a muffler never does boost that much, regardless of what they say) but a flat-head Ford never sounded better!

I am torn between a Supertrapp and Hushpower muffler. I'm leaning toward the Hushpower right now. If I get it should I stay with the 2.25" pipe or step up up to 2.5"? Or will it even matter?

the stock pipe is actually 2" in and out..
Id leave it, and the supertrapp is going to be
pretty loud..
I still like my Walker Super turbo

[ZEUS]

2"? Really? Learn something new every day. I just want to try something no one else has. Thanks for the tip on the Supertrapp. The Hushpower it is then! I don't suppose you carry them...?

[Vehi-Cross-Az]

I dont carry it that I know of, I can see if one
of our whse's has them if you want.

Had my aero muffler for several years - a little loud if you get the one without a resonator - but no other muffler comes close - pricey at $250.
It actually speeds up the exhaust by venturi effect - put one on my diesel motorhome also and the results were really amazing there.
