dynomax VT mufflers

[modularmustang]

Hey guys,
I was lookig to swap in some mufflers in my stang. I currently have mac LT's and a Mac O/R H but with the stock catback. I wanted something about the same volume at cruising but a bit louder when I get on it. I saw these new mufflers from dynomax and just wondering if anyone has any first hand experience with them.

couldn't find 4.6 liter mustang video, but close enough... they sound nice at idle but once he gets one it they sound awesome

opinions on installing these guys on a system like mine?

i like dynomax, but the is something about moving parts in a muffler that i dont like. there is a hinged flap and return spring in there. to much moisture in an exhaust system. i can see these mufflers getting stuck after a few years. especially in a car that isnt used much. i could be wrong though. the dynomax stainless ultra flows are nice.

Thanks for the response.

I heard good things about ultraflows but having a O/R pipe I know a straight through muffler would be too loud for me...

Moving parts put me off a bit a bit, but after a bit of research the flap and spring are both stainless steal and apparently Lexus and other brands use the same sort of things in their higher ends cars. Is it the same quality? idk.

I was hoping someone had tried them and had some insight to their craftsmanship and quality. However looking at reviews from the ultraflow mufflers (stainless steel), their stainless steel mufflers generally do well.

I have stainless Ultraflows on my car with and offroad x-pipe I'll try and get a vid up from when I had the 331 still in it. It was loud at WOT but much quieter than 2 Chamber Flowmasters anywhere else. At WOT it sounded pretty sick though.

I have heard of some people having issues with those VT mufflers rattling. Look on youtube or google dynomax vt rattle.

I put them on my '89 LX becasue I couldn't live with the 2 chamber Flowmasters droning for a half hour straight on my commute to work each day. So far I'm very happy with them. The've been on there about 6 months.

^good to hear, i'm really considering them for a spring mod. DO you have a video/could you make one. I couldn't find any mustangs with them on youtube.
