This "may" raise some eye brows and some asking themselves "What the hell is this guy thinking?" None the less, curiosity and improved engine life, performance and slightly better fuel economy (?) does make me consider the question quite seriously.

The question - Can you buy true "Performance Headers" and a "True Tuned Exhaust System" for a 2007 E350 3.5 ltr V6 with factory fitted Sports Package?

The logic, headers and a tuned exhaust system produce "freer" air flow and reduces back pressure. Therefore, theoretically, that in itself should increase BHP and Torque as well as improving fuel economy, even if only marginally I have read that in some cases, BHP can be increased by as much 40 BHP and Torque can be increased by as much as 30 Torque. The 3.5 ltr V6 already produces 278 BHP I believe so getting it above (fingers crossed) would be a huge plus, especially for long distance/highway driving.

Naturally, there are many other things could be done, a cold air intake, turbo charger, performance chips etc etc etc. From what i can tell, the headers + exhaust offer improved BHP and Torque for a reasonable price.

All thoughts and opinions welcomed. And yes, buying an AMG or Black would be the "easiest option" ...... I wish; although I do know where there is an early model SL 550 pure AMG for sale .....

@tabijan

Thanks, not exactly what I wanted hear but at least I know what is what now. I believe there is a guy who makes custom exhaust systems for racing cars not far from me, at least there was about 5 years ago. Might have to go and talk to him and see if he can't build me the headers/extractors and exhaust.

Thanks Maxbumpo, there are always going to be trade offs I guess BUT, may have to rethink my ideas perhaps. Maybe I should just bite the bullet and go buy that AMG and be done with it.

Um, so your point is ....??

Just kidding mate - point taken and accepted. I really did hope that Mercedes themselves may have had an AMG style header/exhaust system that might also fit my car.

Guess you just can't improve on perfection, especially German perfection 😊

 

[wombat457]

Hmm, okay then ........ the general consensus is that things like headers are a waste of money as they don't really achieve any productive benefits - ahh, to the buyer of them in any case.

German engineering is "possibly" the best in the world, not saying it is, just that it might be AND, certainly better than anything America can produce, so comparing things pertaining to Chev engines might be a bit pointless when discussing a Mercedes or any non American car. Just to clarify that a little, my 3.5 ltr V6 Merc produces MORE BHP than my 350 CI Chev Corvette V8 - so adding anything to an American (Chev at least) engine might well induce some improvements, possibly even significant improvements. 😉

I do have to admit one thing - way back I had a Chevy 307 Holden Brougham which I added extractors to and what was considered a performance exhaust and muffler back then and I actually did get better torque and horse power. I also got really really crappy fuel economy to go with it

Anyhow, think I'll just leave well enough alone and enjoy the precision (and perfection) of German Engineering as it is from the factory. Yu can't go any faster than 75 MPH in "some places" here (US) anyway so, logically, more power, speed, performance is a bit pointless as well, other than (maybe) boasting rights

 

[wombat457]

What is a George Elmer or Barney engine? Plenty of Chevrolet engines that are much better than some Mercedes engines.

Basically any non factory, modified (privately or professionally) engine, just incase you really didn't know.

Thanks gents.
