Has anyone installed this kit? Any HP gains, or is it strictly for a little more exhaust noise?

 

Im not sure what the kit consists of, but if you ask me, its probably a pointless waste of money. Just go to a muffler shop and have them remove the resonator and replace it with straight pipes. What more is there to it?

 

I'm guessing the kit just comes with perfect fit pipes.

 

I just installed it last week.. Paid $205 for 2 16" pieces of pipe..THATS ALL!! you can get this done at a local muffler shop for probly $100 installed. Exhaust note is slightly deeper, not much louder at all.. would not have wasted the money if i knew this is all the "so called kit" consisted of. BTW it also came with a can of spray paint, to paint the welds..

I agree.

 

another one got got.

did they try to charge you $999999999.99 for installation

 

Cost of 32" S/S pipe $10
Labor (cutting to size) $5
Can of paint $5
Exclusivity (AMG, no less!) $185
Another example of AMG "snake oil" mods

 

there is another forum member who did the x-pipe mod and found that we only gained like 3-4rwhp tops! but he did notice a better low end rumble on the exhaust. this was on a W210 E55...if your talkin about a W211, it will be worth it since you have FI. the scavenging of exhaust gases will help tremendously and i would forsee a good 10rwhp increase. this is assuming your stock system is completely individual from headers back. i know on my W210, each bank of exhaust is seperate from the other, so theoretically speaking an X pipe would help...

some exhaust shops can do x-pipes too, but if you want to stay cheap, just hack out that resonator and have a shop weld in two straight pipes... either way, the sound of the exhaust will be a lot deeper and meaner then stock!

W211 E55 already has a crossover in the exhaust system, so there's no reason to do an X pipe.

 

Removing the resonators on a W211 has no effect on HP. It barely has an effect on sound as well.

 

In my e63 the sound increase is noticeable.
I'm sure no gain in hp, as the resonator is a straight pipe with a baffle built around it.
Still sounds good w/ a growl at wot.

 

Probly, but i did the install myself..

 

I was the first one who did the X-pipe on the W210 e55 stock system. the gains were NOT 3-4 they were 5-7WHEEL HP on the top end as dyno proven and not only that but it improved air fuel ratios as well on the top end significantly. The X-pipe is ONLY for W210 E55's b/c they did not have any crossover pipe. W211 theres no need it has a stock H-pipe built into the system. Resonator bypass should not cost more than $100 installed otherwise u got ripped off big time. Just replace with straight pipe on W211s. Also there are NO gains to be had by catbacks on BOTH w210 and w211 E55s they are BOTH 100% free flowing (again confirmed via pictures on benzworld along with dyno). I did extensive research on the entire W210 exhaust system. X-pipe and high flow cats and headers are the only things that will give you more power, normal resonator bypass (just straight pipes) will net you zero since stock resonator is already free flowing (again proven via pics on Benz world).

Moral of the story, if you have W210 E55 ... get the X-pipe. W211 just bypass resonators w/ straight pipe, zero gains but at least it sounds better.

 

I wouldn't be surprised if it made the N/A engine louder. The E63 is much throatier and deeper than the E55 as it is.

I agree. Vic55 was having trouble a while back because he was running an exhaust with no cats. He actually had too low backpressure and lost power.

 

Another common trick is to move the cats further back, this helps improve flow directly off the head while still keeping enough back pressure on the engine to keep torque up. This is a common trick on the E46 M3s (main difference between the US & Euro cars was the location of the cats). US E46 guys could gain up to 10 HP just by relocating cats further back (coulple of feet, and of course using high flow cats will help of course).

Just another suggestion. hope that helps.

 

Evosport Resonator Delete Kit comes with STAINLESS STEEL pipes cut and pr-fitted to your car.

At your local muffler shop you will get two pieces of rust-in-a-minute-made-in-cheap-country-piece-of-too-small-size-pipe to replace your resonator. You get a hack-job that results in crooked tips and exhaust leaks a month later.

Which one do you want?

 

I think this pretty much sums it up. I looked on eBay tonight, and you can buy a 5 foot length of T304 stainless for about $25, so the total cost of parts in the "kit" is easily under $25. Maybe a few bucks more for labor if they expand the pipe up to slip over the existing 70mm tailpipes. The can of paint is as stated. So maybe a total all in cost of $35 or so for the "kit." So what if Evosport only marks it up just over 500%? Do you prefer it standing up or bent over?

 

Well, after i got my"kit". My buddy wanted to delete his resonators in his 07 S600. Our local muffler shop cut, and expanded the ends to slip over the existing pipe all for $40.. and yes they were stainless T304. Same exact pipes i got from Evosport...

 

You guys must be related to the muffler shop owners. You can't get a damn thing done around here for under $100.00 PLUS materials. I'm getting the EVO setup to be able to swap the resonator back in pretty easily. Most important is to try to get rid of a droning I get at 72-73 mph. If nothing else, it'll take 20 lbs. off the car.

 

do they make the EVO setup for the W210 E55???
Aj

 

I didnt know anyone at the shop, just walked in and asked. as far as putting the resonator back in, i dont think that would be possible..

 

Very possible if someone wants to take the time not to butcher anything. I want the option since my car is a lease that I definitely am not keeping. Some dealers can be a real PITA on a lease return, others less so.

There is no pre-made X pipe for the W210's that I know of. The mod made no additonal power in my 2002 E55, but it already had FI. It was a different dyno, but the difference was only 2 RWHP. That's 0 improvement to me. It could have been the difference between the dyno's easily. It could have actually lost a couple of HP, and I wouldn't have known the difference. The sound was definitely improved however.

 

Fast55: i agree, on a W210 FI application, the gains will not be noticed, however, they are still gains... theory suggests that equalizing the flow will net hp gains. maybe not a lot, but still a gain.
for non FI (like me) it should help the motor "exhale" a lot better. removing that resonator is a huge plus already. equalizing the flow is just adding a lil more...Im doing the x-pipe mod here shortly and will post back dyno results. But the main reason i am doing it is for the sound. the exhaust is just too quiet for me. im used to loud exhausts (read, straight pipe 427ci in my vette).

You will want to do more than just get rid of the resonator in that case. It got a little louder, but really, the W210 was still much quieter than my W211 with a completely stock exhaust.
