I work at advance auto, and we carry a muffler made by dynomax, welded, it claims that the performance on it is like 10 X that of a flowmaster, plus its only like 60 bucks. I was wondering if anyone has had this muffler put on an intrepid? or know anyone who has? I'm considering it for performance not sound.
Dynomax Race Welded Muffler on Intrepid?

my understanding about these type of performance mufflers is that they may be designed differently, but they are pretty much the same. (dont yell at me, just think of any real noticible difference in mufflers other than its sound...when installed on an intrepid)...they may be made of different materials, by different companies, but theyre purpose is teh same. i cant see how a dynomax can claim 10x better performance than flowmaster, its the same damn thing.

havent heard of one on a trep thou. if thats what you wanna do, do it. youll definetly notice a difference in the performance of this car.
The Dynomax UltraFlo mufflers do flow significantly more than a Flowmaster, but not ten times as much. 
The UltraFlos are high-tech fibreglass-filled mufflers which have about the same restriction as a straight pipe. I have one on my '00 ES replacing the rear resonator. The sound is not much louder than stock ( which is what I wanted - a lower tone ), but I noticed an increase in throttle response ( which I also wanted ). On the G-Tech I lost about 0.2 sec 0-60 mph, so the performance increase is real, if modest. Had I removed the stock muffler completely and run only the DynoMax I'm sure thae sound would be louder and the performance slightly better.

I guess the dynomax is a better freeflowing muffler. My idea is running the race magnum welded dynomax muffler just by itself, and cut out the OEM muffler and resonator, prob run the dyno out the rear with 1 inlet, and 2 outlet with some nice tips. For about 80 or 90 dollars installed, thats a really good investment on performance. I cant seem to find where these people get their flowmasters so CHEAP! 60$ some people say, lemme in on your secret, reason I turned to dynomax is the price, and found out that they arent to bad of a muffler.
Sorry about the last post, messed up. I checked into the dynomax ultra flow, runs about 70 dollars. I pulled it out of the box at work the other day and it looked really solid. Part number of the one I want to get is 17218. Yeah mine is the type ES. My coffee can muffler is coming in next week .

the cheapo flowmaster 40 i got was picked up by a buddy of mine. its all about connections...
yeah, try out that dynomax. but check first: do you have to replenish the fiberglass inside the muffler every so often? my experiences with glasspax (i HAD a thrush on the benz...literally taped it behind the header so i wouldnt piss the neighbors off when id turn her over...didnt work, though!!) but the fiberglass inside gets blown out gradually over time. you may have to purchase a recharger pack and either re-pack the muffler, or replace the thing entirely. could be wrong though........good luck!

The only problem with any muffler with the fiberglass filling is that over time, that fiberglass burns up and blows out. The Flowmasters use welded baffles inside the muffler, so the note and backpressure never change. My buddy ran a set of Dynomax mufflers on his '70 Chevelle, sounded sweet for the first summer. But after that, it got really loud, not so mellow sounding.
