    My new Marauder exhaust

    Well as you know I installed my Stainless works headers earlier in the year so now I drove the car from WI to Dallas GA
    (open headers, yah it was loud!)

    to have Mo's Speed Shop install my new exhaust.

    H-Pipe, 3" mandrel bent all supplies from Stainless Works.

    When Jeff saw the 2nd pull at 463 he was amazed (all the guys in the shop came running over to see what they had heard). He knocked it back to 14* as I wanted to stay under the magic 450 number with stock block.

    Jeff said there was a lot more in there too.

    BONUS! fuel mileage bumped up to 20mpg too!

    It's amazing what an engine can do if you let it breathe...

    And man... does it sound wicked! Low, deep, rumbley and mean!

    Nice work for sure. What mods were done to the engine?

    Thumbs up



    The 'full story' (mods and such) should be interesting when you have time. Saw Jeff Harris grinning while sitting in the driver's seat!

    450 'safe' RWHP is plently for a 'driver' IMO. I always use the Terminator motor as a reference because many of us felt it should have been the motor Marauder had installed at the factory. 360 RWHP is the generally accepted figure for bone stock Terminators, ignoring arguments over the Mustang dyno vs. the Dynojet. Now that I know where Marty's shop is located, the good hotels and 93 E0 availability in the area....

    4th generation Marauder: I've read anywhere from 230 RWHP to 240 RWHP for bone stock Marauders and 265 RWHP average with a tune, 93 and a CAI. I tell everyone mine makes 270 RWHP!!! I would be thrilled with 360 RWHP and even 450 'safe' RWHP.

    Nicely done! Can’t wait to see it in person.
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    I’ll tell you what you ain’t the only one who drove a Marauder with SW open headers. I drove approx 55-60 miles I’l never do that again in my life. It was too stupid loud and your lucky as hell state police didn’t pull you over for that.
    Anyways it looks good just not a fan of the 4’ Meg pipe sticking out the rear bumper like that. All it takes is one idiot behind you trying to parallel park or whatever.
    I’m also wondering how did you get Stainless Works to custom build you that H-Pipe ? Another thing what size is the pipe after the mufflers ? 3in or 2.5 ? Did you stick with the SW Mufflers ?

    Wow! I would love to get 20mpg with a S/C! I think SW is in my future...get ready Marty!
