Hey all. My car is a 2006 with 73k miles and is stock with just a EC tune and for all intents and purposes, I don't drive ***** to the wall (all the time) and am not hard on my car. I live across the street from work and don't drive it too too much at all.

The other day I noticed what sounded like a small exhaust leak, mostly noticeable when driving along side a wall or through a drive through. Mostly audible at around 2500 RPMs. Anyway, today I was downshifting to slow down coming up to a light and whatever created the leak got louder and now it's just loud. My buddy and I are going to put it up on a lift tomorrow or Saturday here at work and try to get a better idea of where it's coming from. My question is basically whether or not there are seals on the exhaust or perhaps the manifolds in particular that are known to go bad on these '06s/55 motors/cars?

I know that if it's up at the manifold it'll be a MFer and cost a bunch of money to replace/fix. Planned on eventually doing some headers but NOT right now so that kind of sucks. I'm hoping it will be somewhere else, but any input would be great. Thanks.

Keep us informed. I believe I have stock manifolds laying around somewhere. I'll check. And you can have them.

Okay cool. I really appreciate the offer

It takes about 30 mins to remove a exhaust manifold it is super easy. If it is cracked I would take up RBJ offer or if you are in a hurry you can take it to a muffler shop and they can weld it for you.
Also please check your motor mounts because if they are bad the engine will move more which results in cracking of the manifolds.

Long tube header time?

Spot on Not as big of a deal as it may seem

I had the same symptoms and it was the headers (RENNtech).

Check the flange where the exhaust meets the header.


Mine cracked all the way around.

Engine mounts are a problem on these cars. My car had them replaced, twice, under warranty - thankfully, it hasn't happened since I've owned it.

Failed/Poor engine mounts + motor rock under slow/heavy load = cracked headers with a leak sound.

Well thanks guys that makes me feel better about the situation. And Sterling, man I'm all about that I just didn't have the $2000 readily available right this instant. I typically stash money away casually until I get enough for my next set of mods or guns, depending on which way I go lol

Anyone in the Phoenix area know a good exhaust shop? :p

SterlingE55

Amen to that.

My car kind of sounds like a dragster john deer lawnmower..

I don think anyone here has a car louder than mine. I got some new videos we made right before we took her apart. They will be up soon.

Dostovel

Car is in the exhaust shop and it is a crack on the weld line of the right primary cat. Going to re-weld the cat, do an X pipe and resonator delete. $300.

Question though. That's nothing I would want to have EC re-tune anything for, is it?

Next upgrade is going to be new idler pulleys, and SC pulley so should I just wait?

Dostovel

Ended up being $200 lol Sounds great with those deletes, too.

vntgspd

Did they weld the cat on the car or drop the center exhaust section?

I have a manifold crack at the flange and am debating whether I need to remove it.

Dostovel

I'm not sure how they did it. They looked pretty easily accessible though. The dude is pretty good. He does mostly custom ****. A buddy here at the dealership has an old Lincoln Continental and he redid the whole exhaust setup on that thing and it's badass.

He'll be doing my headers for sure when I can pony up the freaking $2000.

By the way, nice color on that E55
