muffler or not?

I have a 5 inch flo pro exhaust with muffler right now and love it. I have been thinking about making it straight pipe but dont know whether to or not? Does it make that big of difference?

How much of a leaf blower sound does your system have? I think the muffler delete will make more of that - good/bad depending on your tastes!

I liked mine straight piped unloaded but it is annoying towing I couldn't stand to have my windows down while towing, wasn't too bad if I never rolled the windows down. I like it alot better with the muffler.

How would you describe the sound with the Magnaflow muffler? How much of the air noise does it remove, how much quieter overall, does it have a deeper tone to it?

I like 5" with a muffler. I am currently straight piped but I will probably put my muffler back on. Less hairdryer sound, especially at idle. It still has a throaty sound at WOT though, which is nice. My muffler is not a Magnaflow muffler, but it's the same exact design with a different name on it.....and it's a hell of a lot cheaper.

The hairdryer sound at idle is LOUD!

I got mine on eBay for $95 shipped. Same exact muffler that Magnaflow offers, just a different name on it.

I see they make the exact dimension of muffler for 4" systems too...
Thanks for the link Jeff - I was wondering if you have ever heard the MBRP M91031 muffler installed backwards like Jesse had mentioned on PSN?
I'm just trying to narrow things down some - snow is melting where I live / spring is in the air / time to play!!!
