I have been thinking about a setup like this, replacing the third cat with a dual in dual out muffler. I found this online http://www.magnaflow.com/02product/ss.htm product-14379

I believe that flowmasters crossflow mufflers would also work.
I think that 95lx has a similar setup.
What does everyone think about this, a bad idea?
Thanks,
Will

i did that set up. i didnt use that muffler tho
remember that if you have a muffler in place of the third cat, you probably wont be able to lower your car very much and it makes an awful drone in the cab.
but other than that i like it

Most guys use the magnaflow dual in/ out muffler for this type of application. Personally I prefer the sound of Magnaflow to that of Flowmaster but that's just my opinion.

I have the dual in/out magnaflow underneath in my setup...but I also have two Magnaflow mufflers at the back. I think it sounds good...and no ground clearance issues

well, from what i've heard, people recommend using 2 x-pipes instead of just one or none to mostly eliminate the drone. so instead of getting the 14379, why not get the 14386 (with x-pipe built-in) and another x-pipe to go either before or after it? that way, you get the sound you want, and eliminate most (if not all) of the highway drone?

and also, from what i've heard (can't verify this personally, as i've not done this myself...maybe someone else can verify this?), having 2 x-pipes helps eliminate the torque loss associated with removing the 3rd cat/resonator.

personally, i plan to use the 14385 with another x-pipe (both 2.25") and then run true dual to straight tips out the rear. but who knows? i may decide to replace everything from the headers back including high-flow cats, and if so, i may do the 14386 with another x-pipe (both 2.5") and then run true dual to straight tips out the rear.

good luck fitting the x AND the muffler midbody...I have the muffler w/ the x inside, and i dont think there is room for much else... no highway drone also, with no cats.

maybe not a pre-built x-pipe, but maybe where the 2 pipes come off the main cats, i could have them come together into a custom x-pipe, then come back out to the dual inlet of the muffler.

or maybe just have them put in an h-pipe right before the muffler, that would probably accomplish the same thing.

thanks everyone

what are the quality of the magnaflow mufflers? It says they are stainless. Would they be comparable to borla of dynomax? Will i have to evuantually replace them?

For the people that have this setup. What kind of prices did you pay to get the pipes bent. Whats reasonable?

Thanks again
Will

magnaflows are very high quality...there like a cross between flow and dynomax sound wise....if that makes sense...i doubt youd have room for the dual in dual out muf and another x pipe uner ours cars.....what makes you wanna do the sinlge dual in dual out muffler?

I feel it may be cheaper and easier than a true dual setup. The art exhaust is nice but too expensive in my opinion. I am not crazy about a catback system because the gains are minimal and the will rust. I know most people go to a shop and have dual pipes bent for them, I live in NY and my car is kept outside. I am trying to get a setup that i wont have to replace. It seems like this setup will be the cheapest, free up the most hp(for the money spent), and last the longest. I dont think i am interested in an x pipe. Would i be able to keep the pipes seperate to the back of the car? I realize there is a very small ammount of room to work with.

Thanks everyone

a single dual-in dual-out would be as cheap or cheaper than 2 single-in, single-out mufflers, and also take up a lot less room, making it possible to mid-mount it easier.....i personally don't like the mufflers being at the rear of the car

i priced the 2.25" dual-in dual-out here locally, and it's somewhere between $100 - $125

I paid 68 for my dual in 2.25 in/ single 2.5 out magnaflow off of a guy that sells on e-bay. Its aluminized but he also sold stainless. What's it matter they all have lifetime guarentees (sp?)?

but we're talking about true duals, not 2-1-2. true duals requires either 1 dual-in dual out or 2 single-in single out mufflers (assuming that you're not deleting the mufflers completely).

that is a pretty good price for the muffler that you got, tho

as far as them all having lifetime warranties, that may be true....but i personally would probably pay a little more for stainless so that i wouldn't have to go through the hassle of taking it off when it rusted to claim the warranty on it. i'd wanna stick it on there and forget about it.

I dont think you'll have any rust problems, especially if mounted midbody. they get quite hot under there ....enough to easily evaporate the condensation. But whatever you wanna do...

check out http://www.fle-online.com for magnaflow stuff. I havent checked ebay prices, but I got my stuff from fle-online and I would definitely do business again. Free shipping :D

would everyone use the 14468 rather than the 14379
because of the x design inside? Will both these mufflers fit?

Thanks again
Will

weswing04, i read that you don't have cats....
how is your muffler doing??? is it handling the heat ok? any issues??
I have two 2-chamber flowmasters in the mid-body with turn downs ( no rear exit) and plan to remove the cats but worried that the heat will be too much for the mufflers...
