i ran long tube headers to true duals into Hooker Aerochambers. was very loud. way too loud. muffler shop added a H but not a true H. sort of a U shaped H in that the connection to the T's was a U for more volume. a half circle. it took the resonance away and quieted the exhaust about 30% which was a lot. day i picked up car i could not believe. sounded like a vacuum cleaner. well not quite. i too considered a pair of resonators as i was getting headaches if in car over 40 minutes.

The sound alone just makes 'em think I might have something waiting for them, so they don't bother... which is fine by me.
BTW, your car must be wicked with the blower. Is it stroked as well? What kind of numbers is it putting out?

Even if the muffler would have the advertised measurements it sure would be a very tight fit.
Can you explain how you made the muffler fit, otherwise I will return the muffler??
I would post pictures to see a comparison between other resonators, but don't know how, can anyone help me out.

Glad to hear the X toned it down. I have LT headers,Hi-flow cats, 3" duel tubes to 3" in/out flowmaster 40's with LT tips. Sets off car alarms and can hear it comming blocks away. Gonna stick an X in now for sure.

Stock center muffler
20 long
8.25" wide
4.5" tall
3.5" center to center pipes
Magnaflow center muffler
18" long
8.25" wide
5.25" tall
4.0" center to center pipes
It hangs down a bit because it is taller/thicker due to it being 3" pipes.
Sorry but it looks like you got the one listed in the above thread and I thought that was the one I had. That one is a 5x11 muffler and the one I have is a 5x8 version.

I bought mine because you said you had the same muffler, that it has a tru-X pipe, and of cource that it fits. Well, none seems to be true.
Your muffler doesn't have a tru-X pipe!!

I got the non SS version. I thought is was odd that they did not advertise it properly too. When I called them I was just hoping that it had an x-pipe in it and it did. I would give them a call to complain about them not listing it as an x-pipe muffler. Maybe we can get them to change their description if enough people call about it.

Eric, do you remember if this was a full 3in dia. going through the muffler or did it downsize? Also, I noticed on Magnaflow's web page, they say it is available in stainless, but when I try to find it, I cant find the smaller size in stainless (12469). I sent an e-mail to the performance peddler (ebay) asking these questions. By the way, it is $94.05 shipped on there.

Well here is what I have found out so far on their web page. The 12469 & 12468 are identical except the 12468 is set up for 2&1/2 pipes.
When you look at the stainless steel versions they have a 14468 which is the same size as the 12468 but it shows the tru x design. They dont show a 3in version in stainless. I am going to call them tuesday and see what they say. I would prefer the stainless version but will use the steel version if not available. I feel sure they just left the tru x part out of the discription. But I will let everybody know.

Well I wanted to report back what I found after calling magnaflow. First, I called 800-824-8664 and spoke to a guy named Jim.
He told me the following,
1. 12469 does have the tru x design,
2. he said it is a stainless version, the aluminized are no longer made. But it is not a polished stainless.
3. He said it is 3in into where the x is and that is about 4in.
For me, that will give me a exhaust system that is 2&3/4 in the pipes and 3in in the resonator and mufflers. Thanks to Eric for posting these mufflers. This should be more then enough flow for me.

So it's a SS tru-X pipe dual 3" in and dual 3" out muffler.

Just to set the record straight, I talked with B&B about the differences between their X-pipe and their resonator installed on their 3" catback. On their dyno, LT4, the X-pipe didn't change the horsepower except maybe by 2-3 hp over their resonator. However, the X-pipe produced "30%" more resonance or noise than the resonator. It seems like exhaust systems are like opinions; everybody has one and each is different. Intertesting thread.
