LCE Long tube header 2trfe 2.7

The ultra grey RTV engine mount mod is doing pretty damn well. Haven’t launched from first yet, but I have soft started then mashed the gas and she isn’t budging much. So far no denting just tapping on the frame there scrapping the coating off. Annoying sound when you get on it, rapid fire tapping.i did get a $3 ratchet strap and try to help lock down the driver side mount… I think that iswhat’s really saving her right now. Ghetto.. but works. It is temporary. Strapping this side down gave me an idea for securing engine mount.. the plate between the mount and engine that acts as a cover/shield of sorts im thinking of changing to a gusseted plate which tabs fan out above the frame bolts. I can ditch factory bolts to use longer grade eight bolt with a top lock nut to sandwich the stock mount tightly to frame. It will act as a dampener but not budge. I’ll play with that idea at work and conjure something up. I’ll post that up definitely. Be any easy upgrade to stock mount to essentially hard mount.

 

I did get a chance to speak with the guys at LCE. They are reviewing my findings and will get back to me soon. I hope some tube rearrangement is in order but keeping that collector flange placement. It was refreshing to have something line up nice for a change, customization really is a headache sometimes so I’ll take wins wherever I can. I look forward to hearing back from LCE. I’ll update on the matter when I do.

 

I do not recommend LCE long tube header for 3rd gens to anyone yet.
I didn’t hear back from LCE so I went ahead and contacted them. They are still in the process of looking into the issue and going over my findings with their fabricator. Not much of an update, but I do appreciate them taking the time to speak with me nevertheless.
Fingers crossed that when they do get to bottom of this, it’s some minor issue. Would be great to hear that it’s resolved and fitment problems like this will be a thing of the past. I will update here again as soon as I hear anything.

 

I got mine for 3rd gen about 2 years ago zero clearance issues and am happy with it, i know its not what you want to hear buying new pricey headers but a simple smack with a hammer to dent the tube slightly will have no effect on performance i see you have a small one but a big dent wont have any downsides. I would do it on some LS v8 swaps back in the day, even with back to back dyno runs to show any changes. Again not what you should have to do to a new header if you heard any sound difference it was not from denting it. Engine masters did a test on this years ago . Its nice that we have some companies still supporting the ol 2tr but quality has gone down and the price has gone up, i mean it matches everything else in my day to day life. Nice dyno graph with the blower how do you like it ive heard mixed reviews

 

Nice! Good to hear yours fit up well from 2years ago. I would be curious to see your header and take measurements like I did these two for comparison. You might have the desired lost template for a good fitting header. As for denting the header and not affecting the exhaust sound, I disagree with you. The first set of headers I got from LCE before it contacted the truck frame had a crisp sound. After contacting the frame and denting the tube, it chopped up the crisp note and also cause misfires at around 3500 sustained rpm. The second header I installed from LCE had no dents obviously, brand new, the exhaust note is crisp and I do not any misfires at any rpm range. I can’t speak to the power numbers not being affected with the dent. The choppy exhaust note and misfire around 3500 rpm is what I experienced.

As for the blower (URDs kit) I do love it. Out of the box it more than doubled power (stage two). My inexperience at the time wasn’t good though, I wasn’t monitoring AFRs didn’t even have the software to connect to the piggy back ECU and I cracked number 2 piston ring gland. That was about a year ago. Since then I rebuilt the engine using LCE’s hyper pistons (compression drop 10.1 to 9.4), “street” valves and springs, balance shaft delete, head studs and main studs. I picked up a laptop solely for tuning and got the Map3ecu software and starting tuning (limited tuning, timing and minor fuel adjustments) and I monitor AFR and boost constantly. The power no is up from my first dyno session, and I drive the crap out this truck. I have 15k on the supercharger as of yet.

In short, l love the supercharger.. buuuut have software handy and tune for your climate before beating on it. And monitor AFRs.. definitely monitor AFRs

 

So, it’s been three weeks. I reached out again to them a couple weeks ago, and there was no update on findings, only that they were speaking with the header fab guy and showing him what I found.
Im giving them the benefit of the doubt and I believe they are looking into this, fixing the inconsistencies, fitment issues and **enlarging the collector flange to 2.5”** (last one is a wish.. It’s only 2.25” currently)
I was amazed at how different the two headers were and so was LCE when they saw my pictures and measurements from this post.
I look foward to hearing from them and seeing how they stand behind their product.
I will continue to reach out to them about this, I’ll post whatever I find or hear about from them.
