Nameless header + overpipe fitment issues

I'll have to take a look at this on the lift. Thanks for all the help with the diagnosis guys.

That metallic noise is probably normal. It was with my revworks/nameless/q300.
Once I removed the resonator it went away/you couldn't hear it anymore. It's a typical stainless header noise from what I understand.

The fitment issue noise is way different.
You may also want to check if the pipe hits the body/tunnel further back. Mine did. You can hear it bang on the floor.

I have this same metallic noise with my set up(ofh, nameless combo w/ resonator). I double checked all connections after install and no leaks so I think it's normal. My biggest problem with the overpipe/front pipe was getting it back in the hanger, otherwise i don't have any clearance issues. There is actually plenty of room around the pipe once in place. With aftermarket headers involved it's really hard to pin point where the problem is. As long as I'm not hitting anything and nothing is leaking I'm good.

Thanks. Hopefully I can get the car up this weekend and take a look. Your install sounds lot like mine.

If it's not the FP/OP or a loose O2 heat shield, I'm not sure what I'll do. I don't really want to ditch the header (considering how long I waited for it, LOL), but the metallic ringing noise does not sound good inside the cabin, even if it's normal. :/

Not to change the subject but how does this setup sound? I currently have a nameless 2.5" axleback with 5" mufflers as well as their 2.5" fp/op with helmholtz and high flow cat. I can't find and videos or comments talking about this particular setup.

I had this exact same setup before adding my OpenFlash header. IMHO it was too loud after adding a catless header. I've since switched the Nameless axleback for a Perrin catback and things have quieted down to be more reasonable without losing the great sound.

Reporting back after putting the car up on the lift today to take a peek at my Nameless FP/OP and OpenFlash header. (I was also swapping the Nameless axleback for a Perrin catback to quiet things down a bit.)

To be honest, the fitment with the Nameless FP/OP combo pipe and the OpenFlash Header is not great. I don't think either part is at fault per se, they just disagree about what angle the flange should be at.

In this picture you're standing under the header looking toward the passenger side of the car, where the header and overpipe meet. The OFH flange is on the left, the Nameless FP/OP flange is on the right.



You can see that they meet up perfectly on the bottom, but there's a large gap up top. Tightening down the bolts to close up this gap is what pushes the FP/OP up out of the tunnel between the subframe and the engine and puts it very, very close to the engine. Tightening this up is also what pushes the back part of the pipe away from the hanger, making it difficult to get back into place.

There's basically zero play in the header. The FP/OP is the more flexible part, so it gets screwed when these flange angles don't line up.

In this picture, you're standing just off to the side of the header on the passenger side, facing the rear of the vehicle. The header/overpipe connection is up to the left.



You can see the tunnel between the subframe and the engine where the overpipe is intended to go. Notice how the Nameless pipe is kinda being screwed here and is forced up to the top of this channel, where it comes really, really close to the engine. We stuck some white paper behind the gap so you can see how tiny it is.

So now that I've readjusted everything, I'm pretty sure it's not the FP/OP that's rattling against the engine. There's a very thin gap that I had to watch carefully while tightening things down (it's easy to end up with the pipe against the engine if you're not paying attention). Unfortunately the metallic buzzing has not gone away. I'm back to guessing it's the O2 sensor heat shield. I tried to pry it away from the header today, but I couldn't get a screwdriver down in there very well.

If I did this again, I don't think I would get the FP/OP combo pipe. I think I would get the factory fit front pipe from Nameless and a dedicated overpipe. I think that would give you just a bit more wiggle room which would really help with fitment issues like this. The rigidity of the FP/OP combo pipe is great, but it leaves you up a creek if the header flange isn't absolutely perfectly positioned, because you're not going to get any play out of the header.

Hope this helps.

Got the Nameless header along with their 2.5" overpipe/frontpipe. I'm running into a fitment issue with their overpipe. It's hitting the head and causing an exhaust leak at the top of the gasket.

Anybody else running this combo have the same issue?

look to the left of stud and nut holding on your header. there is a fat tab of aluminum its just an extra piece of cast. i cut mine off because is was touching my overpipe. even if its not touching now this will give you some room to adjust the overpipe in that direction.

sound clips pls

Replaced my FP/OP combo and happy. "Metallic sounds" are gone now. No additional rasp w/o Helmholtz resonator. Just sounds a bit more "throaty" and the UEL "boo-boo-boo" could be heard more clearly at idle inside the car.

Why I did not buy normal separate pieces from the very beginning?..

On the attached pic the point of contact with the engine block is clearly visible. The pipe spent about 3000-4000km on the car.

Here a video of the noise issues I'm having after installing the Nameless header plus mid pipe.

[ame]http://www.youtube.com/watch?v=LqOZUlfgluk[/ame]

What's the vertdic? Metal on metal contact or VVT noise from the E85 tune?

My fiitment issues are the same as everybody else that has posted on this tread. Super low clearance between the mid pipe and block. I think I'll try the move the engine around tomorrow.

[ssyed]

Yep, I've got the exact same issue with JDL headers; its touching the engine. There was no issue with the stock pipe and JDL headers. I did manage to get the nameless pipe installed without any leaks and rattle. However, I'm pretty scared about it touching the engine.

Thinking about contacting nameless. Wondering, if any of you gotten this replaced? If so, did the new replaced pipe have the same issue?

[Imrac]

I had mine replaced and received one that had slightly more clearance then the previous. Although the fitment is acceptable now, I would not recommend the product to others.

Also, Nameless was kind enough to even pay my return shipping.

[kbye]

I knew there would be issues with fitment just by looking at the design.. I was worried by the lack of bends on the OP to DP section and this thread sealed it for me. I ended up buying the tomei OP and I'll probably get the factory fit nameless DP.

[Brinks]

My noise issue ended up being an increase in VVT noise, Nothing to do with metal on metal contact. The fitment is tight but there is a bit of room for manipulation.

Like what others have stated earlier in the post, loosen the bolts to the CB, header and remove the bolt on the transmission hanger. Remove the engine mount nuts, grab the engine from both sides with your hands and try to tweak it a bit so it favors the passenger side. I also put some upward pressure on the passenger side of the block when I tighten the bolts down (33lb) Last step is to go back and tighten everything down while being cautious of the placement of the down-pipe.
