Just recieved Mugen header........DC SS header comparison
............and I think I am going to have to retract a few comments made by myself comparing the Mugen header to the DC SS header. TO be all honest, the top half that bolts to the head is very similiar between em both. I still think the DC is a very nice quality header even compared to the Mugen, but there are some differences that I need to adress.
Collector: The inside diameter of the DC sports header is 1.9". The inside diameter of the Mugen header is 2.3". Both units welds to me are clean looking(though yes the Mugen is better, but its still negligible to me).
Some nice touches: The mugen does come with a new head gasket,sticker(for sale for $220....)and excellent instructions complete in Japanese(this may or may not be a problem for you if you only read English). BUt one thing I did not realize was that the braket that bolts to the oilpan under the car is not welded onto the Mugen unit. You have to weld it yourself. Some people have complained of the DC Sports header bolt plate being welded a bit too far forward(not the case on mine though). WIth the Mugen install the header and the bolt plate, then weld the bolt plate to the header itself. Soooo, there you have it. I am taking some detailed comparo pics tommarow, and will be doing a dyno within the next week, though I can see the Mugen making a few more HP as people claim already with the larger collector. So my interest will be in the torque band. I will be interested to see how the torque band compares to both products.
Is it worth the money?? To be honest I think the DC is a nice unit and for the $400 tag isnt too bad. But the Mugen isnt worth $975. If it were priced around $600 that would be much more reasonable and in line in all honesty. But it is nice to have! Matches nice with my Mugen Showa coilovers which I just love.
I may pick up the Mugen exhasut to complete the package.......my question on the exhaust is this, what is the diameter?? Is it 60mm??? MY DC Sports is 60mm and I am very ahppy with it. Neel if you're reading this let me know the specs. And more specifically let me know if the piping tapers down to where the exhaust is supposed to bolt to the cat converter, the DC sports does unfortunately and I now have a test pipe in place of the stock Cat so I need to get rid of the 1.9" bottleneck where the exhaust bolts to it.
Personally I feel every Mugen part is overpriced but the header is most worth it. I've only read good reviews of both quality and power it adds. I've seen a Mugen in person more then once and each time I'm very very impressed. I would say it's worth $800.
Another great thing about the Mugen header is resale value.
^^ very true....they're all overpriced....but considering the alternatives, I would also agree that the mugen is one of if not the best....the exhaust is mostly a preference, but the header is better....cept that it's overpriced. just look at the mugen sticker an intake
I wish i had the answers for your questions, but I don't.
My guess is that it does taper down, seeing how i am still running a stock cat. convertor. If you had problems with the DC sports exhaust, my guess is you will have the same with the Mugen cat-back.
Are you still going with the JRSC? You probably don't need a mugen exhaust and header if you are going with FI.
yeah mugen is over price ... just name brand
honestly i probably trust DC more.. due to the fact its cheaper so everyone can afford it .. so they have to make millions of people happy.... they are life time warranty too which a lot people dont know... dunno about mugen ... but i think they wouldnt give you another set of headers with out putting up a fight.. they gonna lose $900 if they do that.. so i say DC is good enough...

^^ good point....I thought bout havin them replace my header cuz of the broken bracket....then I thought....it's a hassle to get it off, put the stock one back on, get the new one, take the stock one off again, an then put the new one on again...just to have the bracket break again :: maybe if it gets worse, then I may do it.
Mugen b-pipe at the cat flange is 51mm ID (54mm OD)...thats about 2" ID...so yes, the mugen b-pipe is smaller from the resonator to the cat. Everywhere else is suppose to be 60mm though. Here's my post from awhile ago mugen inlet/outlet
Btw, did you compare the merges. Mugen's look amazing to me, but I have no others to compare to. My Mugen exhaust will be here soon, so I can confirm the size of the piping and take pics or other measurements, if need be.

I knew you would come around once you saw the Mugen header in person
so ritteri you have mugen headers wtih ur JRSC ? how will it perform with the JRSC ? where did u get a hold of the header now a days, i heard they were discontinued

the header is not discontinued, they are providing those still because the accord is using the same header. the exhaust is what was discontinued. To be honest, I had a DC ceramic header with my jrsc, and I switched to Mugen, but my butt dyno didn't feel a difference, although I don't regret the change.
whats really sad is the fact that you 5th gen guys cant use the greddy SS header....well u could, but youd have to go straight pipe...no cat.....i had a DC header....then i got the greddy one...wow...its impressive...my 1/4 mile times dropped 2 tenths, from the DC and my mph went up 2...the greddy simply performs...id say its my best mod so far.....i ran consistent 14.3s...with the DC...using AEM cai, DC header/apexi exhaust/vafc/skunk2 cam gears......i also ran the 14.3s open header which helps your top end...however , im now running consistent 14.0s with the exhaust hooked up...i ran once open header and hit almost 102mph in my traps....if you want a good header, and are gonna run a test pipe anyways...grab the greddy...peace

That's interesting. When I compared the Mugen to the DC header, the primaries were obviously longer on the Mugen. The secondaries also appeared to be larger in diameter, but I did not measure them.

Negligible? Hmmm....have you looked at the cross sectional area of both? If the DC is 1.9" ID, then that's a cross sectional area of 2.84 square inches. If the Mugen is 2.3" ID, then thats' a cross sectional area of 4.15 square inches. That means that the Mugen has a 46% larger cross sectional area, much better for exhaust flow on the top end, I would think.

I would think that the Mugen would do a little worse on the bottom end, and better up top with the larger tubing and longer primaries. As for torque, again, I think the DC might have the advantage on the bottom end, but that's going strictly by theory. There have been plenty of comparos that I have seen where theory and reality were just opposite of one another.

If i had the kinda funds he had i'd stick with F'I see how much i could squeeze outta of the lude, and enter gumball 3000 and be the first lude to represent.

JG Luder has had his Lude accepted to the 2003 Gumball 3000, he will be the first, and is running a big-ass turbo.

Matches nice with my Mugen Showa coilovers which I just love.
