Default Replacing Flowmaster

Well i've seen enough posts on here to know that my flowmaster may sound really great, but that's about it as far as benefits. So is there a good muffler (not catback) i could buy to replace it with that won't cost me much, sound good, and give me better performance. Or is it worth it to just get a whole new catback next spring? Thanks guys!

I would give a Magnaflow muffler a shot. I bought mine because I was told that they flowed well. It will probably be quieter than your flowmaster and the tone is a whole lot deeper. I think that Dynomax mufflers are supposed to flow pretty well too, but then again single in/single out mufflers would probably flow better than most crossflows do.

Yeah, i may just wait and get a whole new catback, even though i would have no idea which to buy but that is a whole different topic. Magnaflow might be interesting, but i'm not looking to get quieter, i like the way it sounds now. I have put dynomax systems on some different applications and haven't been impressed, is it any different for the Camaro? How does the dynomax sound/look?

They are certainly not as loud as the RustMasters, but you'll be hardpressed to find a better flowing muffler than a Dynomax in general. If you're basically looking for a stock replacement crossflow then I'd look at p/n 17227 Dynomax UltraFlo Welded. I'm thinking that's the right part number, but I'm not sure what size your I-pipe is.

Take a look here: http://www.dynomax.com/documents/ultrafloweld_specs.pdf

If I remember correctly Jeg's carries them for a good price.

Does anybody know the flow numbers on the Flo-Pro twister series mufflers? I contacted flo-pro directly with questions about there twister series mufflers.. and they answered all of my questions except for that one. So, I sent another email asking the same question again. No response as of yet.

Thanks,

Spyder

I know that there are a bunch of you out there with the loudmouth set-up. And srh00z, i listened to your clip of the magnaflows, and they sound good, but seem a bit too quiet for my taste. Like i said, i like the way my flowmasters sound, just not the way that they flow <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Do the Dynomouth mod.
$40 muffler and around $100 for professional install. Great sound and flow to match.
I have sound clips, pic links, and mod tips on page 2 of my website.
Good luck
Dave

I think you need to think about exactky what it is you're after. Do you want a certain sound? Do you just want loud as hell? Or do you want max flow? I like the Flowmaster sound - I've had both 40 and 50-series versions over the years. Their flow numbers are generally poor though. The Dynomax doesn't sound as good (IMO) as the Flowmaster, but has great flow numbers. A deeper, more mellow sound is how I'd classify it. The Loudmouth will be louder than a Flowmaster setup for sure. How much louder, I can't say. You'd need to get two equivalent cars, one of each exhaust, and a decibel meter together to quantify it.

If you want a combo of loud and high flow then the LM is a great option. I think Tbyrne was selling them for $299 recently. That's hard to beat...

I want better flow and a sound similar to my flowmasters, perhaps a bit louder, but not any quieter. I want to be heard from down the street, but want to be able to hear my passengers speak (most of the time at least) If i have to shell out money for a catback then so be it. Wouldn't really wanna spend over 500 bucks. This is more of a springtime plan, just want the info now. I'm hearing that Hooker makes a decent system.

I replaced the stock muffler on my 'bird a few years back with a Dynomax Super Turbo muffler. I was very disappointed with it. I think it was quieter than the stock one it replaced. Just a few weeks ago, I replaced it all with a LM and absolutely love the results!
