Any idea on who sells long tube headers for the S65? Getting my car the first week of march and want to do all upgrades at once.

TECHNICIAN

There is no such thing

Someone told me about this and sounded extrage due the turbos, but I ventured to ask.

Does the cat delete help in any way?

OP there is plenty more power to be had.... But is not happening with headers! As it goes I'd be tickled to have exhaust that flows better then all the sharp turns MB made for our M275 engines.

Upgrades.... K&N air filters help. A reflash for the engine and trans ECUs is said to be helpful at vaporizing rear tires faster.

Fooling with exhaust will make more noise.... More stink out the tailpipes.

She makes 740lb/ft stock. See if that isn't enough first! That an she will almost certainly need some attention. Get all that caught up first. If it still needs more... Enjoy!

Thanks for the reply!

It will be my first car with more than 350hp, but also heavier than 3,000 lbs.

I know it will be a learning process, so maybee I should just get to know and get usef to the "black sheep's" power.

I ordered the Kleeman ECU because its tuned for 91 gas and we can only get up to that here in Puerto Rico

LOL..... My 221 S-65 is 5200lbs that bends and cheats the laws of physics... At a cost. The number of '300 HP sporty cars' she leaves for dead is forever amusing.
