New to the Marauder, exhaust advice

[Noremac1993]

So I just bought an 03 SB Marauder and I'm reading through all these posts for exhaust and I'm just super confused... I'm looking for exhaust that has a deep rumble, I don't want raspy, but I also want exhaust that will be good for later on boost application.


It seems like everyone has 2.5" exhaust. Is that enough for a supercharged car, shooting for 450hp+? And can you just buy a complete 2.5"+ exhaust system from the headers back? I will upgrade headers when I put the supercharger on. I could really use some help, but please explain things because I get confused. THANK YOU in advance.

2.5 is plenty to 600 rwhp. kooks offer headers and mid pipe, stainless works has headers and 3.0 exhaust.

These cars don't really have a deep rumble but you can eliminate raspy with muffler choice which vsries greatly on preference. go to you tube and search marauder exhaust

This doesn't sound bad, but they're sold out, and kind of expensive.

I have 2.5" and make 750 rwhp.

03 SB with 18K miles.

Unsure if you know this but there were only 417 SBs built in 2003 so you have a rare Marauder.

See where you are in the build sequence of 03 SBs and Marauders by ordering a certificate from Ford:

And this is also raspy unless you don’t mind buying another set of mufflers.

im just going by what someone told me once. i knew 600 was a,safe number, i should have worded it different, thanks for letting me know it is higher than i was led to believe.:beer:

they make them as needed, about a 5 week turn usually. There are no exhaust companies that make marauder systems except stainless works, you can put any muffler you want on, but it will need welding etc. welcome to maraudering, nothing is cheap to getcwhere you want it to be.. Wait until boost comes into play...$6k - 25k or more

Welcome to the site. I have a full stainless works system on my car can confirm rasp. Nice system otherwise.

Don’t waste your money, add mufflers to your choosing and delete rear cats. Then when supercharged add headers and h or x pipe... and new front cats if you wish. Just my .02 cents

Borla Mufflers sound great, not raspy.
