Great quality, slip fit was crazy easy to install, had the old one off and this one on and bolted in 30 minutes. My only complain is that the tip is a bit longer then it needs to be, couldnt pull it any farther forward with it hitting the uncarriage. Have a youtube video of it idling uploading, ill try to capture some more video this week, trying to thaw out right now. It's louder then stock at idle, but very quiet when you are at part throttle, then it gets louder when you get into it. I also threw a 3" cat onto the ebay long tube downpipe.

 

not sure if that came out right lol

 

very nice man. that first pic looks like it sagging extremely low though

 

Yeah the tip seems kinda out but looks good

 

It does hang a bit low there, im going to double check the ground clearance for that tomorrow, but theres no other way to fit it unfortunately. The stock pipe did sag there as well though.

Yeh it needs to come back about an inch, i might evaluate if I can cut some of the pipe down behind the muffler where it goes into the slip joint and see if i can bring it back a little bit.

Looks like my nexus 5 didnt take good video up close so Ill try again with another vid tomorrow.

 

Here's my exhaust tip. It doesn't stick out as far but looks like I need to adjust it up a bit. Are you sure you've got every joint slipped in as far as it'll go?

 

Ill have to double check them, pretty sure they were all tight, but I also dont have the same bumper as you, i have a SS/NA bumper which does not have that lip that extends out that far.

 

Ohh maybe thats why it looks weird because of the lip it looks like its more in but maybe its not

 

well no idea whats goin on, took it for a drive today and its beating against the trunk at idle from the shake of the motor, gotta put it back in the garage tonight and check the clearances, also gonna try to re-adjust that tip. The whole exhaust gets burning hot, which I was kinda surprised to see. Almost burned myself when I grabbed the tip to get it to stop shaking. OEM exhaust never got that hot at the very end.

 

Hmmm thats kinda weird. And yeah when i installed mine it rubs alittle sometimes but i dont really mind lol

 

Got the tip to go back about a half inch by pushing it further into the pipe, and we added some rubber to the upper hangars to prevent the muffler from going too far to the drivers side, it was apparently banging on the bumper. Whenever i made a turn it was sliding towards the drivers side on the hangars and making contact.

 

Glad you got it adjusted. I am waiting to adjust mine until I get the other downpipe. Hopefully it'll be here Wednesday.

So your muffler was sliding around? Did you notice if the hanger holes were elongated when you reinstalled them to the new exhaust? Mine were tight. I had to use some dish soap to get them on.

 

I could probably have done with some new hangars, but they werent beat to where they needed to be replaced. Problem was the hangars on the muffler were so long, and the tip is wider then stock, that it was sliding along the hangars when the car shifted from side to side in a turn, so I needed to add stoppers to prevent the muffler from sliding on the hangars. That kept it dead center in the bumper relief.

 

I have a bit of sag going on in the same area as you. The problem is, with the piping tucked up like it should be, the hanger behind the muffler is basically floating. driving around and going over bumps, the exhaust pipe bangs against the frame above the rear axle. I'll have to keep adjusting it to see if I can get the pipe up a bit more but not too high as to make a rattle. maybe i can figure out a way to put in a little rubber bumper above that area to keep the occasional rattle from happening.

 

I would get a couple new rubber hangars and stack them on the pipe side hangar so that there is very little play once you get it into position. Im probably gonna have to do the same in some places, or smack the pipe a bit where it comes close and dent it to get a couple cm's more clearance. Also probably gonna have to remove the heat shield above the resonator. Gonna take some tweaking but you will get it.

On another note, do you have a very distinct burning smell coming from yours? I havent been able to get rid of this smell coming from the muffler side, smells like burning hair or something. Checked the entire path of the exhaust and its not making contact with anything, and my bumper appears to be fine.

 

Why do you need to remove the shield above the resonator? Mine has plenty of clearance there. The only smell I'm noticing is the new stainless heating up and still a bit of anti-seize burning off the bung caps, O2 sensor and manifold bolts. Maybe the smell you're noticing is the resonator baking. Aren't they packed with fibers of some kind? I haven't ran my exhaust for more than about 30 minutes so far. Maybe I'll notice something after it heats up a bit more.

Post back if you find a solution for the fitment issues. I'll do the same. Id hate to have to dent piping for clearance. There's got to be a sweet spot for getting all the angles right. I would hope ZZP has calculated all the bend angles as they should be but it almost seems like there's more fine tuning they could have done. Certainly we aren't the only ones to run into this?

 

Oh im sure ZZP calculated all the angles, but the chinese company remaking these things for them (OBVIOUSLY NOT MADE IN HOUSE) sometimes gets the pipe angles wrong. The heatshield above the resonator was actually the first thing to hit on my car, and we had to hammer it out. I am not sure what this smell is to be honest. lol They are supposed to be packed with fiberglass and steel wool, not horse hair. LOL

 

Lol.

 

Wierd, any exhaust ultimately gets hot to the touch lol. Mine used to hit around the torsion beam, just takes some readjusting.

 

Oh i know the exhaust gets hot, but ive never had one so hot at the tip that you would get burned, im talking the very edge of the tip where its sticking out past the bumper. The burning smell has to be coming from something burning inside the muffler (packing im assuming) which is causing it to get that hot. Frankly im amazed the bumper hasnt melted just from the radiant heat around it.

 

Any updates/luck with fitment?

 

ill let you know this weekend

 

I've been in contact with ZZP over the last couple of days. I've tried everything they recommended. They even put one of these systems on one of their 2.2 shop cars and filmed the install (still waiting for the video link). After spending several hours trying to get it right, I've surmised there really is only one way for these systems to go in. Meaning, there isn't much room for adjustment.

 

Here are 2 photos they took while installing this system on their car. Notice their S-pipe is running nice and flat up against the body.




^this photo really doesnt show anything helpful to me

My S-pipe is hanging down 2.5" away from the body.





^These photos are how I have mine installed.



^ This is the area where I'm getting contact. The pipe is banging against where the hanger is welded to the body. In this photo, the hanger at the back of the muffler has tension on it just like it should be. With it installed this way, the muffler is centered in the rear fascia as it should be with a nice gap all the way around the exhaust tip. If I adjust that S-pipe up towards the body(where it should be), this hanger on the backside of the muffler raises up to parallel with the body side hanger. Thats when/where I get contact while driving. Also, with it adjusted that way, the exhaust tip isn't properly oriented in the rear fascia opening.



^ Here's a video I filmed to show the issue. Note, I still dont have the S-pipe up as high as it needs to be. With it up higher, that issue in the problem area gets worse.

ZZP says this kit should be tightened with an impact. I used one but it didn't seem to change anything for me. They have been great about this. They've responded to my emails and have offered advice along the way. As I said before, there really is only one way for this system to be installed. There is minimal room for adjustment since the pipes between the resonator and muffler both have several bend/angles and hangers welded on. If you twist one pipe, it affects the angle and height of the other one. Since I can't get this right and by comparing their install photos to mine, I suspect there has to be a bend out of spec. I work in manufacturing, these things happen sometimes. People get tired, they rush, sometimes people cut corners. I'm not saying for sure that's the issue. Its just my suspicion. I asked ZZP if I could bring the car in so they can see whats going on. They said no problem. I just have to find a day that works to get there.

 

My S pipe definitely hangs lower then yours, ill have to snap some pictures in the same locations and see how much different the clearance is. You might be able to get away with the back and forth movement by adding an additional hangar or replacing some of those hangars that are sagging. Ill have to snap a picture of what we did on the muffler to actually get it centered so it wouldnt smack the bumper.
