Hi,
I've been a member for a long time, just haven't been posting a lot.
I just recently sold my 2010 E63 and got a 2014 E63 S
It's going to take another 7-8 days till I get my car shipped to Idaho but when it gets here I would like to go ahead and get a tune downpipes and bridge pipes most likely from Kleemann.
This is where I need your opinion and help.
I've been researching a lot even before I got the car and am familiar with all the Tuners and Shops however, from my research I found out (correct me if I'm wrong) that Kleemann is the only company that has not only the Downpipes but the Bridge Pipes as well. It seams like that all downpipes are about the same or very similar and according to my research the downpipes give about 15 hp or so...but if you do the Bridge pipes with downpipes it will give you about 70hp give or take. Another thing that I was not aware of and found out recently is that if you decide to go with bridge pipes you have to take the engine out for the install.
AMS Renntech and Weistec seam to have dynos and very attractive numbers posted on their website but I really couldn't find any dynos or info on the E63 AMG S since their information is about the 2012 m157 I believe. I know the E63 AMG S is underrated and has about 607 hp at the motor so a tune and downpipes advertised by companies mentioned above cant add an extra 140whp-170whp am I right ? If those numbers are correct do these companies include the bridge pipes but don't mentioned them or do they have a totally different design? Maybe a representative of the companies mentioned above can educate me on this subject..or maybe a forum member that has them installed can give me more info.
Thank you very much for your help..and sorry for the huge post

Congrats.

We also sell turbo back down pipes (same as bridge pipes)

FYI since you have a AWD car the engine will need to come out in order to install the turbo back / bridge pipes

Just got my 2014 last week. In for the info.

I'd like to add AMS with their Alpha tune seems to have the most HP/TQ increase. Have you noticed this? Who are you looking at for your tune?

Where in Idaho? I just moved up to Meridian

I would suggest not to get the turbo back downpipes, I have them installed and I didn't gain any extra horses on the contrary I lost whole bunch of torque. Get regular downpipes

chiromikey

Can you define "a whole bunch"? I don't believe the turbo back section is worth as much as we'd like to think but I also don't see how it's possible to lose a lot of tq.

Just curious, did you do before and after dyno? I plan on installing them in the near future.

I made 520 whp before carless turbo pipes and 544 after like I said nothing different to other dynoed E63 RWD, dynoead again with tune (Eurocharged) and netted 620 whp, again nothing impressive, I've seen higher dynos same tuner on the same mods minus the turbo backs. So I think there's no real gains there unless you are upgrading the turbos.

nikon

Interesting! Did EC adjust the tune for it? I wonder why is Kleeman claiming 70 hp with their exhaust. Maybe someone that has it can chim in.

chiromikey

Still trying to figure out where your "lost a bunch of tq" statement came from...

CarHopper

70hp to a tuning company is likely in bhp (not whp) assuming as high a drivetrain loss as they can get by with (so probably 20) and perhaps a little rounding up.

Don't pay too much attention to claims anymore. Most of them are heavily inflated.

nikon

Apologies, I didn't specify it is 70 bhp. It would make sense just by looking at the original and aftermarket turbo pipes. The 70 bhp from kleeman is the entire exhaust up to the rear mufflers. The more interesting thing is that the peak hp is up higher in the rpm range. I've noted that most tunes out there are out of steam close to the 5000-5400 rpm range. Weistec and Kleeman swear by the turbo back exhaust. Renntech doesn't. As for AMS, if one adds their carted down pipes and the rest of the exhaust, the claimed gains are around 50 bhp.

You guys do understand, different dyne's will read totally different. Even if its the same type of dyno but it could be calibrated differently as well. Even Temp/Air density will play a huge role in what the dyno will read. The best way to use a dyno is to use the same dyno while trying to get the same conditions on both comparing runs. There you can actually compare the full graph on each dyno and really read what has changed.

Just food for thought bro's..

Turbo back pipes are not worth the cost of install on AWD cars. Just get the regular catless Downpipe.

I'm right by the Village Ustic and Cloverdale cars and coffee starts this Saturday

Thx for the info..I'm probably gonna go with Kleeman talked to Brian in Colorado that is an authorized kleemann dealer/shop and really liked what he told me. They have a great set up and it's very affordable for just about 7k I can have turbo back downpipes with the tune and filters installed (includes taking out the engine) Claim is about 760hp at the motor backed by dyno its their K3 package..not bad compared to a lot of other companies. Plus kleemann has been doing it almost as long as Renntech

Romeo_f

You can see my stock dyno on this thread:
https://mbworld.org/forums/w212-amg/...l#&gid=1&pid=1

And I attached the after with turbo back DPs installed. You be the judge.

kponti

You would be the first. Please post before and after dyno

nikon

Are you going with their complete exhaust from the the turbos to the rear mufflers?

chiromikey

Are you asking me to compare two different dynos?

byroll01

That's crazy. I spoke to kleemann in Colorado today too. I was told $7500 for the turbo back alone...

727E63AMG

Did you call this number 719-473-6441 ? I talked to Brian he is the shop owner...

727E63AMG

yep

Will do , going to take me a month or so before I can get it done..my car is being shipped right now...so once I get it will take it to the Dealer to get everything checked out..drive it for a month and then take it to Colorado...car is still under warranty so would like to make sure that if anything needs to be fixed it gets done before the warranty is voided
