Thanks, it looks like a lot of work to get it to fit right. I'll see if the shop can adjust it a bit more. They had to file that corner down a bit to fit...but it's still touching. Hate to have to hit it with a hammer to fit. It should just fit! So frustrating...especially for the amount of time I waited for these.
Ideally you could get a properly fitting pipe that fixes this from Dezod. The question is the hassle factor. It's probably less hassle to just fix it in place than it is to get a new pipe but that's sort of a personal decision. It looks to me like the pipe was simply a little short. Even another 1/2" would move it off the crossmember.

You really have two choices. Fix it now and drive on or wait and get a replacement pipe from Dezod, assuming they don't just tell you the people installing it fucked up.

Dezod is denying any issues with their product. Suggested to loosen the manifold bolts & vclamps, then adjust and tighten as necessary. Perhaps that will fix the issue. Just not sure why the shop wouldn't try that. Hope that's all there is to it & hope the shop will adjust it for free.

Another way a friend suggested is to cut and weld a 2 inch pipe extension in there. I was thinking of a 2 inch pipe extension, with flanges on both ends and I can just attach with vclamps. Hope I don't have to do either.

Yeah, well most people are fuckups.

Assuming Dezod uses a jig when they make these things, it's very likely they're right. It assumes though that they didn't screw up too though. Looks to me like the vband clamp might be what's forcing the pipe into the crossmember. If it was just a little straighter, it probably wouldn't touch.

You've just highlighted a primary problem with paying someone else to install your mods. You now have Dezod and the installer at odds and you're stuck in the middle with a rattly car. You have no real way of knowing who screwed this up.

I'll bet that ball-peen hammer is looking better every day.

2" is a bunch. You'll force the whole exhaust back 2" To make this work, you'd have to add 2" at the header and then remove 2" in the exhaust someplace.

Man, I bought the best header and paid a reputable shop to install so I won't have to deal with headaches and excuses...turns out I'm dealing with both! I guess if you want to have something done, you have to do it yourself. Everyone is so nice until something goes wrong...then it's always someone else's fault. If I had installed it myself, the blame would've been put on me. It was mentioned by Dezod that my car had been in an accident and the brace shifted...anything but the product. Yet no picture or description of how much the clearance should be.

Yeah, that hammer is looking pretty good...lol

I would be pissed. Paying a premium and having issues is the worse.

It's hard to know who to blame though. Dezod might have sent a perfect exhaust and this is only an install problem.

I think Dezod gave good advice. Loosen all the bolts and try shifting things around. It doesn't look like it's that far out.

Yup, going to give it a shot...that's probably the easiest way to get this thing right, instead of hammering, cutting, welding.

Bolt on, should just be Bolt on. Not weld on, tinker on, tweak on, etc. Like plug n play.

Yup, not only paying a premium, waiting 2.5 months for product...waiting during install...

Dezod seems to make some nice stuff but face it, nothing is as good as OEM. I'll bet Lexus spent more developing the OEM exhaust for the IS than the budget of the 10 largest aftermarket IS parts suppliers. And that's just the exhaust.

They then spent a billion or two making a factory so the exhaust is mostly the same for every unit they build.

Most aftermarket parts are hand crafted. The good companies use jigs and get it pretty close most of the time. The Chinese junk on Ebay is best effort.

Then you have these "speed shops". In my experience when I walk into the door, I typically know more about my car than they do. Took my WRX to one for an alignment (these were subaru "specialists) and they had to call me into the back to show them where the adjustments were.

You're expecting too much from these people. Like you said, the only way to get a good job is to do it yourself (or leave it stock).

I have the exact same problem! I have also taken the car into an exhaust shop and asked them to double check everything, reinstall everything (except where the headers bolt to the block) and it came out the exact same. Same alignment, same proximity... etc. Quite disappointing when you feel excited about a "PREMIUM" product that you paid top dollar for only to have an issue that sounds cheap and metallic like some ricer civic.

Maybe you guys with more experience can chime in...I've been thinking that the best course of action to deal with the issue (without having to deal with dezod or custom fab anything from the actual product) might be when I replace the stock piping and muffler. Want to upgrade to 2.5" and something aftermarket muffler. Since the dezod connections are V-Band but the stock parts are bolted (like at the next downstream gasket) when the new exhaust components get put in, have them rotate the bend near the cross member down and away (maybe 1/2 to 1") and weld/bolt up/install the new piping to keep the rattling piece in place where it wont rattle any more.

I don't think it would be enough to make the exhaust vulnerable to scraping (not lowered, but if I do it will only be an inch) and since it's rotating mostly about an axis and has a flex pipe installed it shouldn't mess up flow or create stress or thermal expansion type issues either.

asn007,

Looking to get rid of your stock headers? I'm looking for some options but trying to stay as close to stock/low cost as possible because I'm keeping car as a DD dependable and looking to Turbo so no point in spending $1000+ on exhaust that I'm going to not need later.

Looks like I'm not the only one with this issue as Dezod made it to seem. I'm going to try loosening the manifold bolts, then pushing the headers back as far as it would go, then tighten. Even a few mm back and the pipe wouldn't be touching the bracket. Maybe loosening the vband and twisting it will give a few more mm of clearance.

Hope that does the trick as I really don't feel like we should need to cut/weld/hammer/tinker with a premium product that is marketed to be bolt on.

Have a feeling we aren't the only ones with this issue so hopefully someone that fixed this issue will chime in.

I'm curious to see how this comes out. I'll be watching this thread. From everything I read and see people say, these are the headers you want. If I don't find some OEM ones around me I'll definitely be looking for Hi-flo cats/new headers.
