I've been around quite a few different exhaust setups on the Mark VIII's but none like this. I'm upgrading my exhaust to 2.5" stainless and want to see if anyone is running this setup.

For one day I had an x pipe (in place of 3rd cat) and straight pipes on my 97LSC, it was the most obnoxious fart canny rice sounding POS that i've ever heard. Lasted one day.

I got a pair of LMS mufflers for the rear and it really quieted it down giving it a great sound but I am sick of the grand theft auto sh!t cans hanging out of the rear of my car. Yes, I can get mufflers installed so I would not see them as much out of the rear but I would like to really clean up the tail out back with straight pipes only or dumps.

I've heard a 97 base (single y pipe) sounds GREAT with no mufflers out the back and most guys that run straight pipes only do not have dual exhaust, if they do they have the 3rd cat in place not removed.

I have been in DLF's car with Kooks, magnaflow X mid muffler, 2 magnaflow rears and that is a GREAT sounding car. Resembles my current setup but much healthier and throatier, as it should be. Yet quiet while cruising.

The LMS exhaust, dual x pipes to double rear mufflers also sounds great and that is more of the sound I am going for, partly in reason for having some gargle and popping in the exhaust under high rpm deceleration. However as mentioned earlier, i do not want those mufflers hanging out back, i'd like to clean it up, lose weight, and save money if possible, that is the least of my concerns however, but would be nice. I only want to make one trip to the exhaust shop, order the parts, have it put on and be done.

I'm thinking of running kooks with 2.5" dual exhaust, high flow cats, to an x pipe, immediately after a single magnaflow x muffler, then straight tubing the rest of they way out to tips or dumps.

It will mimic the LMS exhaust with the dual x, yet incorpate an x muffler into the mix.

OR

I could also run two dual x magnaflow mufflers back to back then out to straight pipes. That way i can still run two mufflers to quiet down the raspy fart can sound, i still get the dual xpipe and i lose "junk" out at the rear

Every little thing on these cars affects the exhaust note, from the pipe sizing to the muffler location/quanity, use of resonators, cats, or x pipes and the location of these items. I only want to do the exhaust one time and have the pipes cut once.

So are any of you running dual exhaust, with or without kooks, to a single MID muffler, whether it be an x muffler or not, with or without an x pipe, and straight piped all the way out the tail?

Thanks in advance
 
My set up is BBK longtube headers no cats to a magnaflow 2 in 2 out internal X muff. Then in rear I have "rear muff delete pipes" and a set of magnaflow muffs. I choose which ones I want to run. Without the rear muffs its kinda loud track only for me. With the rear muffs its just right. Like goldylocks. I don't know what the deal is with double X's but I have no drone and it sounds sweet.
 
what size piping are you running?

So with a single mid muff, no cats, long tubes, to muff deletes its to loud...do you think two high flow cats would quiet it down some?

I dont mind the "loud" @ WOT but i HATE the raspy farty import sound. Gargling, popping, etc is ok.

So for you, 3 mufflers is the goldie lox zone, sounds about right. That's how DLF's is setup is but I feel as we should be able to have a quiet enough car without 3 damn mufflers. lol :rolleyes:

I have two mufflers currently but they are at the rear.

I'm really wondering how a back to back internal "double x" muffler would sound at the middle of the car.

I think the reason for the double x is drone, i have a single x, and there is some drone, but its not bad...theres always goin to be "some" drone.

Whatever this guy had on his thunderbird sounded awsome (thunderbirds sound nearly identical to marks in stock form), he lived down the street from me and used to drive past my house everyday, it wasn't obnoxious but at the same time it was enough to hear him coming from inside my house, and didn't have any annoying raspyness or drone like a chambered muffler..his info states it is a modified ART? system with mid mounted magnaflow dual in dual out muffler and im gonna guess 2 1/2" mandrell bent pipe out the back with no mufflers in the rear, one of his pics show his first exhaust system with some funky setup with both pipes coming out the back next to each other, the one i remember exited in the stock location though..

I just looked up ART looks as the posts were back from 03-04 nothing recent. Not sure what he had on there

Glad he changed it...those look silly coming out in the middle lol
 
Yes cats at as mini muffs. Mine is all 2.5 dia. As you can see in pic you cannot fit 2 back to back internal X muffs in the space.

I don't think there's enough room for both a Magnaflow "X" muffler and an x-pipe, and definitely no room for two "X" mufflers, and I'm not sold on the need for two anyway. Magnaflow does however, make longer "X" mufflers. Mine has a 14" long, 4"x9" body (p/n 14386), but they also make 18" long, 5"x8" body and 22" long, 5"x11" body (which I don't think will fit in the tunnel) "X" mufflers.

If you like the way my car sounds, why not just do what I did? The rear mufflers that I used (p/n 14211) are tucked up quite well, and really can't be seen unless you get down to ground level.

BTW, I also have high flow metallic cats.

to save weight, you could probably find some smaller diameter mufflers/resonators for the rear, and use a X-muffler for the center.

I chose to use a Dynomax X muffler, sounds great but I chose not to use any resonators/mufflers in the rear. It's a little bit louder than I wanted but hopefully some Kooks will mellow it down some. Otherwise, I will probably get some resonators installed in the rear..

I actually was just checking your car out a little while ago on your site.

14" long , great to know. I know it would be tight, but a 12" X could squeeze in there. I'm gonna check to see how small magnaflow makes the internal x muffs.

You mufflers are definitely tucked up nicely, i would just like to not have any out back without it sounding like crap

Mid muffler?

checked out your sound clip, nice car, sounds good.

Well, Magnaflow does make the 4"x9" body "X" mufflers with an 11" long body as well. You might be able to stuff two of those in.

But if you do, you'll spend nearly as much for mufflers as I did, with no guarantee that it'll sound the way that you want.
 
Is your main goal not to have muffs in the rear? Also why so crazy for 2 X's? Just more money.

I just searched them, that should fit indeed.

They also make a 22" muffler which has a larger body so may not fit.

I think a 12" x and a single 11" would fit in there or two 11's.

You are correct, I dont want to spend money and not be happy with it. 2 mufflers would be cheaper then 3, and single x with a single muffler even less money.

The dual X mufflers would be purely to quiet it down, not for the XX mantra around LMS or for drone. I suppose I could go with a longer muffler in that spot, but I'd almost guarantee that two mufflers would be quieter then the 22" (which probably doesnt fit anyway) just due to the two separate bodies, both which containing an X and i've never heard or seen it done here.

Every other combination, but not that one...at least not at the mid section of the car, which is where i'd like them to be placed.

Dumps after the pumpkin would be great, who needs the evap tray, they all rust out anyway...lol :rolleyes:
 
Dumps are noisy, I don't think you'll like the way the exhaust sound will resonate under the car.

Yes, my main goal is to not have mufflers in the rear if possible.

I'm not crazy for 2x's, as stated earlier, I only have one x on my car now, could have easily installed a second...haha and I didnt.

The thought behind two back to back mufflers is soley to quiet it down and lose the rasp fart can sound..instead of two at the rear, it would be two mid section, and i know from experience that will change the exhaust note.

Mufflers placed at the rear will be more quiet then mufflers placed in the mid section , however quiet isnt so much a concern as the raspy fart sound...at the same time I do not want to go deaf...so one muffler only may not cut it...even most mustangs have two..center mass of the car..not one, not 3 three.

I only suggested a single X in front of the single X muffler to help with the drone/rasp that would be created with only using one single muffler on these cars will have.
 
Dumps are noisy, I don't think you'll like the way the exhaust sound will resonate under the car.

I've had them before and depending on the application I do like them but even then, as mentioned earlier every single thing effects the exhaust note drastically on these cars. Dumps at the rear would be even louder not just because of resonance but because of the lack of piping to the rear. That would almost definitely need two mufflers.

Thankfully with dumps, if i didnt like them it wouldnt be much $ lost or time spent cutting them off and finishing them out to the back, however I was just kicking the idea around...the rear would look empty without the tips, even though I have a sleepy valley rear valance I could modify and lose the exhaust cutouts completely if i wanted.
 
Here you can see my 2 sets of rear pipes. If I ran NO pipes at all I would get exh smell in car. I scored the 2 SS magnaflows for like 30 each off Amazon till they found there mistake and marked them up to 100 each. SCORE.

nice man, thats a sweet deal :eek:
 
Mine is Kooks into 2 1/2" pipes into a Magnaflow dual 2 1/2" in and out mid mounted X-Pipe resonator. With dual 2 1/2" pipes the rest of the way back. IT IS LOUD. To loud for a daily driver. I've hear Dynomax also makes a dual in and out mid mounted muffler and some member on here have one. I think they are not as loud. Supercharged Lincoln Mark VIII Vs Callenger SRT-8 - YouTube
