Drivetrain my new Megan Racing 2-piece header!
my new Megan Racing 2-piece header!
I got in the 2nd version of the Megan racing header today. I went with this one because of the 2nd piece that has the test pipe. I am probably going to have the stock cat welded in place of it after a couple days,I just don't like seeing the SES light, even if I know why it's there and it's no big deal.
Here's a few pictures, it appears to have good looking welds and nice, thick flanges....now..anyone have install instructions?
Anyone else have experience with this header?

Looks nice, my friend bought headers and y-pipe from Megan Racing for his G35 and everything looked nice. However there have been lots of accounts of the welds cracking and a friend of mine had his test pipe crack on him (Civic Si). Although, people have reported that after you get the welds fixed, should they crack, it is perfect and they don't have any problems with it. Good luck with the install and I hope you don't have any problems with the header.

Your header looks nice.I dont really understand why the cat delete sections are there outside of just disguising the fact that a cat is not being used or just allowing a connection point.In our area we have roadside emmission spot checks so if your car looks modified you or maynot get a visual and then a emmision test.Is it the same in your area?
that sounds pretty harsh, no, we don't hanve anything like that in south carolina, luckily, SC is too full of backwards rednecks, most of whom have straight pipes on the camaros...so 'emissions be damned' seems to be the modus operandi of the government here...
but, like I said, I am going to have the stock cat welded in there in place of the test pipe, one for the fact that I hopefully wont have a SES light, and two because I actually do care about the environment

I installed this header just after the Holidays. Had a few problems.
1. If you look at the exhaust flang to head you'll find that the opening does not match the size of the gasket. I machined all of the openings by a 1/4 inch. Now more closely matches the head exhaust ports.
2. You can install from under the car up on jack stands.
3. Watch the 2 bolt header flang. The hole is almost the same size as the bolt head and can pull through. Use a washer at bolt head.
4. O2 sensors are a tight fit. Precat 02 needs to be rerouted to get enough length.
5. Header with test pipe is short by about 1/2 causing problems connecting rest of exhaust. Also exhaust is slightly higher and now rubs heat shields.
Other wise a big difference in power.

It was painfull to install since it was a little shorter man did I have to pull on the exhaust to get the bolts on... it was so bad tha I went to Home Depot and got me a set of bolts 1/2 longer hehe
.not to mention that it was hard to get it up into the engine bay, since they are a little wider near the gasket than stock.
I have mine rapped with www.designengineering.com so I can lower the temp on the engine bay and I also added the stock header cover ( a little modified). amazing temp drop by the way.
now, I had them for a while and I have not gotten the check engine light once!
not to mention that the power gain is hudge from mid-top but specially up top....

so, it isnt that bad... compare for example to the OBX header...
I didn't notice any fitment issues or anything like that. It does, however, sound like an exhaust leak. But now that you mention it...If I'm having the same gasket issue on the head, the smaller diameter openings on the gasket may be fluttering, causing the sound...so I'll have to look at that this weekend. Mine came with washers for the two flanges on the test pipe, so that wasn't a problem, the o2 sensor we did have to move around a little to get to go in (precat) Of course, I threw a code I'm assume because of the test pipe. So I may be getting the stock cat welded on just to get rid of the light.
But yeah, huge difference in power. what exhaust are you guys using? I've got the magnaflow and together it is loud. And right now it sounds like a WRX with exhaust at low RPMs...I can't even really hear the supercharger anymore...haha...maybe I should get a resonator...

I'm happy iut fitted right for you! So you got a code? weird... I have had mine for a while and nothing...
oh, you can always emulate the test pipe O2 sensor... and the emulator is about $20 plus shipping
other than that..
I also have magnaflow and it does sound loud! but I love it!
I also have Intake which I built (kind of looks like the Alta) and with my 19% pulley! trust me I can still hear my SC

So, fitted the header already?

one person raised a question about weld quality. I doubt that's the problem. I had none of the problems listed there, I may have the first, I'm going to go in there and take it off this weekend and see if I can figure that one out.
