As in just cut off the stock muffler and install a Bullitt Race Muffler? How did it sound and what did you use for a tail pipe?

Thanks.

I put a race magnum right before the pipe goes over the axle (a la loudmouth). Then I just connected to the two factory exhaust pipes together. Sounds great, I love it, and its about the cheapest catback you can do, my 3" in 3" out race magnum was like, $45 bucks. Cost you a few bucks to have an exhaust shop to tie the two exhaust pipes together.

well i have LT headers and no cats and at idle is is pretty damn loud. ove 2500 and it is crazy. at WOT it is "going to jail" loud!!!!!

it is only a race muffler. i have it, but i am an idiot! <img src="gr_images/icons/wink.gif" border="0"> the most free flowing. go for it for sound if you like loud. cheap as hell. if you dont like it, not much lost at all!.

I had that 3 inch dynomax race magnum bullet and swapped it for a Dynomax Ultraflo Welded 3 inch. They both have the same cfm rating (1000+cfm) but the Ultraflo is WAY better in terms of noise control. I have NO resonation with the offroad Ypipe and everything sounds great. WOT is great too.
Hope this helps.

I have Mac Headers With Off Road Pipe and a 3 1/2" Dynomax Bullet which is a little loud but I don't mind. It's still my daily driver. Only bad thing is that I got a ticket from a cop that was 2 blocks away since he heard me and caught me speeding <img src="gr_sad.gif" border="0"> .

I also purchased an Ultra-Flo welded 3" muffler and plan on installing it next weekend. Does anyone have the exact flow specs on it?

According to David Vizard, you need 2.2cfm per horsepower, so at 1000cfm it would become a restriction at 455HP.

I purchased the Dynomax 3" intermediate pipe and over-axle pipe from Napa for $90 and haven't figured out exactly where the muffler is going to go. I was thinking right at the rear bumper, but didn't want it to look ricey. I'd rather use a plain-jane turndown for the V6 look <img src="gr_images/icons/wink.gif" border="0">

Has anyone done this type of swap? I was also wondering how much weight I might be losing going from the WS-6 style to just the Dynomax.

Thanks,
Mike

Here's the link to the specs-

Here's a link to my page with pictures of the muffler and .wav files of it revving.

As far as a weight savings, your not going to see a big difference. It is quality gauge metal. If you want to save 7lbs. ditch the trunk cover.
I can't say enough about this muffler. I had a SLP DD, and loud mouth on my 01. The loud mouth was quiet at idle and shook the car apart at partial throttle. The DD was as quiet as the factory set up.
The idle on the DUFW is nice and deep and roars at WOT without any resonnance.
I don't see how you could get better flow, you can see straight through it.
Be sure and coat it with high temp paint for a long life and looks.
Good luck.

I looked into getting that one to replace my LM "resonator" but it didnt seem like it would fit down there.

Is the Ultra Flo welded muffler available with a dual outlet?

Where the heck are you guys buying these mufflers? I have mac headers and off road y-pipe and the sound between 2100 and 2500 rpms is driving my wife nuts. It literally sounds like a machine gun is firing and hitting my heat sheild back there. It don't bother me but I have to do something. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

So, do any of the sponsors sell the dynomax mufflers??

Thanks,

Thanks all. What I think I might do is add the Ultra Flow Welded and a cut out at the same time.

I am not sure sponsors sell these things, but here is a link to look at.

The dynomax race magnum I had originally was a bullet muffler. 3 inch straight through with 4 inch diamter case.
The muffler I have now is the dynomax Ultraflo welded muffler. Still straight through (can put your arm through it) but is oval shaped like a regular muffler. Great sound control and power.
Cheers,
Chris
ps- I made my own catback very cheaply. Dynomax intermediate pipe for a 93-95 F-bod. Cut off the bend in the intermediate pipe (93-95 had a different cat location) and that part is done. Used the 3 inch ultraflo off of the intermediate pipe in the stock muffler location then bought a single piece 90 degree mandrel bent 3 inch tubing from dynomax and then and chromed three inch tip.
Ran a cutout in the intermediate pipe and I was all done. Total cost was under 200 bucks including installation and there isnt a 3 inch muffler that outflows that dynomax.
Hope this helps,
Chris
