I want to make my 351w sound more aggressive. Can I just install a Flowmaster Super 44 muffler? Is it worth installing? Also, is it hard to install? No y-pipe, catback, straight pipes, etc. Just the $90 muffler with my stock exhaust.
Thanks!

ooooor you can just cut of the muffler, Cat's make great mufflers already

if you run just the cat there is no performance gain, just louder. the flowmaster will give you good exhaust note but may give a drone when you are cruising at a strady speed.

It's soooooo hard not to flame....


If all you want is noise, cut your muffler and cats, weld in a 3" pipe with a turn down before the rear tire. This will save you $90 of the muffler and give you lots of (crappy) noise.

Thanks for your replies.
Isn't cutting the muffler illegal? And dangerous since the fumes are being poured out underneath the car? Also, I don't want it that loud. Thanks.

No cutting the muffler is not illegal (at least in VA) . Just put a pipe to replace the muffler. Run it before or after the rear tires to the side. Just dont run the pipes out the back of the bumper (fumes in the cab when you roll down the back window). Here is a few videos you can hear my no muffler exhaust:


My setup on my 351w:

Y- pipe off the headers.



Magnaflow cat


Y-pipe where the Muffler was


Pipes out both sides


Video:


Sounds good IMO so just some ideas for ya. :rockon

It is NOT LEGAL to remove and not replace your muffler with an EPA approved aftermarket or stock muffler, check EPA tampering laws.

I hate Flowmasters, after checking them out I think my next muffler purchase will be Spin Tech or Dynomax.

im sorry but no muffler just sounds awful... You can get the exact same sound by just letting your muffler rot out, then it'll sound like every back woods country truck...

A chambered muffler like the flowmaster gives the engine such a nice tone. Running no mufflers out of the cat doesn't really have that nice throaty sound and flat out sounds like crap. Watching the video above it seems like it only makes noise when the driver presses the gas...just horrible.
