Never heard of the mod you just mentioned, but the muffler delete would be the first thing I would do. Find a set of tips you can weld on and you're good to go. You'll love the sound. Plus you save some weight too from getting rid of those gigantic mufflers!

So cut the back box off add some pipe with the tips and job done. Sounds easy enough. What about the middle mufflers would you recommend them aswell?

Cheers peeps

If its a 2001 and later its a 5.5-liter supercharged V-8 with over 450 WHP. You're not beating him without a poweradder of some type, and those types of mods seem to hover around 10k for everything. A muffler delete may sound cool [loud and drony] and reduce some weight in the tail, but I doubt its going to add more than 5 HP. I plan on going with replacing my rear mufflers, but for me its mostly cosmetic and for the sound.

You'd be better off getting a Helcat or some other big stonk muscle car if drag racing E55 AMGs is your goal.

Here are the 2003-2006 Merc E55 AMG stats

Mercedes-Benz E55 AMG - Drivetrain/Specifications:

Type 5.5L Supercharged V-8
Displacement (cu in / cc): 332 / 5439
Horsepower (hp / kW @ rpm) 476 / 350 @ 6100
Torque (lb-ft / Nm @ rpm) 516 / 700 @ 2650

You S62 is not beating that. Mercedes purposely made this car to be a M5 beater.
I guess they got tired of getting ******* so they added a supercharger.
