2005 C55 UPGRADES
-Evosport headers
-Evosport ECU upgrade
-Quaife LSD
-Evosport resonator deletion kit
I am looking for some opinions on these products.
tune wise, depending on your budget, I would say the LET/Eurocharged tune, which is at a very very competitive price, (contact Loungn14 (Jake) about that) or a Renntech tune.
LSD is legit
you don't need an evosport res deletion kit. you can get it done for half the price at any exhaust shop. additionally, you can delete your secondary cats or opt for high flow secondaries and see some gains there as well as a louder, more pronounced V8 grunt.
...i'm seeing an evosport theme here....and i'm not hating against evosport, but there are other products out there that perform the same or better AND priced more competitively. being that you are a new member, i recommend also looking into products by MBH, LET/Eurocharged, Renntech, and AMS.
again, depending on budget, you can also throw an intake on there, do a true dual exhaust




i guess i shouldnt say they are worthless....but rather, there are better options available.
Jturkel is correct, depending on which route you want to take there are a few options. If you want shorties then AMS has C55 ones in stock ready to ship now for under $1199 w/ free shipping. If you want a power pulley as well that is also available.
For the Long Tube header route MBH is king plain & simple... no other header on the market is better period. However, they do cost a tiny bit more than ours

I have Kleemann headers, Kleemann ecu, kleemann straight pipes, deleted cats, deleted resonator and k&n filters and make pretty good power over stock.
If you want to keep your OEM primary cats, short tube headers such as AMS and evosport are the way to go (but yeah, mild steel WILL go bad eventually even if its ceramic coated).
The census is pretty much clear that long tubes/tri-y headers such as MBH and kleemann will make more hp than short tubes but one can argue that the primary reason why long tubes make more is because they get rid of the factory cat.
Now I haven't seen dynos comparing shorties w/straight pipes compared to long tubes with straight pipes but I will have a dyno report on a gain with my kleeman headers/ecu by saturday.
Good luck to whatever path you take!

Tune- Eurocharged
Quaife is good option for LSD.
No need to buy a resonator delete "kit". Any custom exhaust shop should be able to do it. Its just piping
I bought them for $2995.
