I had read somewhere on here, maybe over on ls1tech, that the x-pipe mufflers dont give you any real gain since they are mounted farther back than a conventional x-pipe would be. They are also preforated inside so the crossover effect is limited.

Yea, I'd go from the 3.0 collectors to dual 2.5", with the x-pipe and dual mufflers or a good dual in/out muffler...I've heard that if it's dumped it will drone, but with the right mufflers on there you may be OK. I had an exhaust thread recently and someone posted up how there dumped exhaust system didn't drone (search "my turn for an exhaust thread"). I like the external x-pipe better than the x-magnaflow, just my preference. You could do the exhaust, then if it drones, run pipes over the axle and dump it back there, maybe a little higher off the ground, that *should* take care of the drone if you have it. I'm going to run single 3" with an 18" 5x8 Magnaflow dumped before the axle...have a feeling that it's going to be loud and drone like a sonofabitch, but drone doesn't bother me...I actually like to open up the sliding rear window and just listen to the sound of the exhaust, it's music to my ears

i have the longtubes and ory now with the stock catback pipe with a 3" magnaflow si/so welded on. its 18" too. Love the sound. but i have lots of leaks with the y pipe. also like i said i want that f body sound.
I may sell the y pipe and magnaflow and get a x pipe and possibly a dual in dual out 18" dynomax possibly?

Don't think that I've heard a dual in/out Dynamax, but if you have and you like the way it sounds, go for it Choosing a muffler is tough...a muffler that sounds one way on one set up can sound completely different on another, depending on what's going on in front of it...

wonder how two bullet mufflers would sound
edit = been watching you tube vids. most of the cammed f bodys with headers x pipe and dual 18" bullets sound awesome. Think i found my new setup. gotta order it all and sell this y and magnaflow now.

Well you're going to have the F-body engine, now try to duplicate the F-body exhaust...check LS1Tech and see what the F-body guys are running. There was a guy here who put a F-body muffler in the back of his Silvy a while back, it was pretty cool...very different, I like that

I would have to agree with the posts above. You want the "X" as close the the engine as possible, and buy a good one. They are not all the same. I would say you are on the right track with the bullets or DI/DO muffler. Will you see any increase in performance? Maybe, but you are after sound more than power. The "X" will help you to find the F body sound you are searching for. From my experience, if you run the pipes out the back, you will be more likely to get the sound you want. Post up some pics and sound clips when you get it done! Good luck!
