CNT H-pipe Issue
 

Did an inventory got 5/6 gaskets and 10/12 bolts but that's not a big problem.

The H pipe came in two pieces, one side has slits and the other doesn't. The side with the slits is barely larger but the two pieces don't fit together and there is no clamp included. Am I supposed to just jam(deform) these two pieces together and not clamp them? They couldn't have forgot to weld these two pieces together, could they?:confused:

From what this picture shows (CNT's website) you just jam the two ends together to form the "H". It probably would have been a better idea to include a clamp with it to reduce the possibility of a leak.

LOL another CNT exhaust issue......mine came with a clamp to clamp em together........ but i had other issues........ =/ take a picture of your mid pipe. i wanna see if yours is screwed up like mine was. Don't bother contacting them cause they will just tell you to go to Autozone and buy a clamp yourself or they might have to go and get it for you.

The thing is they don't jam together; I'd have to widen/flare-out the piece with the slits to have it fit over the other side. Instead of a clamp would it be better to weld the H-pipe together once its on the car?

I'll have pics of my mid-pipe up. One of my mufflers also has a dent/ding from shipping. This exhaust has been out for a while; they should've had all these issues sorted out by now.

wow that looks like crap!!! i had no idea the two pipes are inserted like that. so they are worried the flanges wont line up and go with this design to compensate. crap....

You would think so but lookin through their thread, a lot of people have had different issues. Though still issues. Seems like they have ZERO quality control at all. They probably realize on each piece what they screwed up but send it out anyways! This is the issue with my mid pipe.

This is the bracket that does not belong! They welded it on the wrong side and only HALFWAY fixed it. Its cut already cause me and another member on here cut it ourselves cause this piece was rubbin on the driveshaft after the HFC install.....

why do i say they halfway fixed it? Cause if you look at the red squares on this one, they grinded down the mis-weld and cleaned it up already. I noticed it before i installed but didnt think anything of it.

Since we are here, heres what ERZ (aka CNT) sent me when i told them i was missing bolts.

Dear chrischhorn,

I don't have any extra and would have to go to home depot and buy it. But I think it will save you more time if you go get it yourleft. Just normal screw.

Thank you

Dear erzperformance,

Hi i just received your exhaust and put all of it on and come to realize that it is missing the screws that hold on the adjustable tips. Any way that you can get those sent out to me?

- chrischhorn

ya they had an issue with one of the brackets in the center. just remove it. IIRC correctly there are 4 brackets, so just cut the one rubbing off. yes the center piece is a very tight fit, but it just takes spreading the cutpieces out a little then it slides right over.

^ okay that makes sense. seems like a crappy design since it would only really fit tight the first time.

hey chrischhorn, I got the same issue with the mid-pipe. It's easy to make the assumption ERZ is knowingly shipping "bolt-on" exhausts that require modification to fit; and that they can't be bothered to replace the missing bits and pieces.

maybe we can rename this thread the "you get what you paid for" thread.

^ its alright budget has to meet performance somewhere for me. Probably why I don't have a nismo.

:iagree:

what can I use to spread the pieces?

WOW......... Man I am sorry this happen to you. I'm surprised they sent you the exhaust even though they messed up on the welding. I would be pissed too. You would think that one would not receive damaged goods especially from welding.

i feel like the only person that didnt have a problem with putting this exhaust on

^ make that two lol.

It ISN'T an issue with stock cats. It only became an issue to me when we installed HFC's. If i were you, i would go ahead and cut the bracket off just so it isn't an issue in the future for whatever reason. Either way as stated, you get what you pay for so im not mad by any means. Just letting others know my experience and what i did to fix them.

By the way, i hope you bought it off ebay cause they have it posted on ebay for $50 less then forum price.........:ughdance:

I don't plan on changing my cats.... should have left it on.

Doesn't make a difference. Just an unnecessary hassle for you lol. Doesn't effect the durability of it. Wont cause vibrations or anything. It was just a random extra bracket to start.

edub370 & scionide, the two of you are pretty effen lucky then. Not sure if everyone else had some drugged out, or hung over SOB put their pieces together.

^ haha. yeah I had trouble getting everything to line up too; muffler's hitting my swaybar. I live in a small town; no exhaust shop is open till Monday.

mine went on great no problems at all... but i did have that little cross pipe welded instead of using a clamp

I didn't have any problems either.

I got done installing my exhaust on Friday and really had to muscle the flanges to get them lined up. There's not enough clearance between the mufflers and rear sway bar, the rattle was horrible. It was so bad that the screws holding the exhaust tips in place fell out....

The exhaust note isn't bad, the price point is good, and I really like how quite it is. The fact that they knowingly ship out exhausts that are missing accessories and you have to cut a brace to make sure it deosn't f'up your driveshaft is a major issue with me.

I pm ERZ and got a prompt response they will ship the screw tips at no extra charge. +1 for customer service.

Must be nice.....i already posted the response from them when i didn't receive the bolts at all. I guess they like to pick and choose who they help. Good for you though.

^ i was suprised. must have been a different person. try pming them.

^ I was suprised and happy.


ERZ response to the brace question and muffler hitting the rear sway bar-

"What you need to do is put a radiator hose and cable tie it on the part of the exhaust that hits the sway bar this will eliminate and rattling noise you might have. What is your shipping address I can reship you 4 of those screws that is not a problem. There was three brackets weld on to the mid pipe one on top and two on the bottom the two on the bottom won't hit anything since it's facing the ground so you saw off the one on top?"

You were happy with that??!!!

Wow, ok.

exactly.......wasn't even gonna bother em with the brace on mine cause i knew their response would basically be "derp derp derp fix it yourself. derp derp derp." Hell I was too much of an inconvenience to get screws for my tips....

Nah mine was good too... a bit of a tight fit but overall no major problems (other than their packaging really being poor). I plan on upgrading to a FI within the year but have no qualms about the CNT exhaust. I've actually gotten a few compliments on the sound.

Oddly enough I had one of the first batches and they cut off the 4th brace after finding they hit... are people saying they are now making them with the four braces again?

This is what i was wondering about too. cuz i purchased on of the batches with the 4th piece cut fof as well and it seems that cnt forgot that this was an issue and just said f it
