That's what I've got on my Grand Exhaust.

That size is the closest match to the OEM mufflers.

Thanks for the info.

What is the stock pipe sizing?

What is the stock pipe sizing?

Depends where you measure from. Stock mufflers are the smallest at 1"7/8 - Over the axles pipes are 2.25" Mid pipes are at about 2"or less and factory H is 1.5" I believe.


Get a muffler where the overall length is 25" or more which is close to what you need -anything shorter and the shop has to add pipe.

Edit: those magnaflows should fit. They are 24"

Midpipe is between the headers and the "H"?

If so, can I run Kooks x pipe leading to the custom magnaflows?
Reason is not sure about going full LTs yet.

Your not going to find any pipes "off the shelf" that will work on a Marauder. You'll either have to modify it or get custom work done.

[BLACK SHEEP]

Are the Kooks Lt or SW LT and Xpipe 2.5"?

Do I need reducers and adapters or do they simply clamp on to the factory pipes?

[2,4shofast]

That is what I am running as well

I don't remember exactly. Just get 'em and take it to your fav shop.

may i suggest the Jones Max Flow line up over Magnaflow, better flow & cheaper.

OK I got a great deal on these from Advanced Auto parts because I was working there part time. I put the car on the lift and found:

1) the mangaflows dont have the hanger hooks on them like the factory ones do.(no way to hang them from the rubber hangers attatched to chasis)

2) you have to cut the tailpipe side of the muffler off and weld or reduce/adapt the pipes to the new muffler

3) on the clamp side of the muffler the O.D. is the same as the factory Hpipe so you cant slip fit and clamp there either.

I know it can be done by someone who knows how to weld but I still want to be able to take it apart if need be. Anyone have pics of how you did it? Im starting to think I might just leave it stock. Im used to mustang stuff that just bolts on!

http://www.fullboarperformanceexhaust .com/servlet/the-template/fullboarlineup/Page I would love to hear how they sound in a marauder with an x-pipe.
Magnaflows and x-pipe is the nicest sound yet.

they sound basically identical, they are the same basic muffler, but with a better flowing internal core

heres how they sound on our Crown Vic kit with an apex-style X-pipe
