ok guys. i'm stupid, don't know crap so please school me on this

how much more power gain? 2.25 vs 2.5

dose mugen come with 2.5? or 2.25? for the usdm?

what about the mugen B pipe, cat? ? are they also 2.5 for the jdm spec mugen?

i've heard that people moding the mugens to get the all the kinks out???
where are the kinks be?????

i'm looking to get a complete mugen set up, header, b pipe, twinloop & carsound cat (or Jdm cat but don't know what the difference are?? ). is it worth the money?


thanks

Don't know, but since they cost the same, get 2.5"

USDM Mugen is 2.25", JDM Mugen is 2.5" (these sizes are approximate, collector sizes are actually measured in MM and are a little less than 2.5" and 2.25").

Mugen exhaust (b-pipe and muffler) is 60.5 MM. Both JDM and USDM have a smaller diameter section (56 MM) before the b-pipe resonator, which Mugen wanted there for some reason. If you order a JDM header, get the JDM exhaust as the b-pipe is longer and will make it easier to find a cat.

If you get a JDM header and exhaust, this shouldn't be necessary. Even highly tuned cars do not seem to be restricted by the Mugen setup (EP has 200+ whp).

Mugen header, Carsound cat, and Mugen exhaust will cost you a little over $2,000. If you want a setup that improves on the stock ITR exhaust system, but doesn't compromise quality or reliability, then yes, it is worth it. The Mugen components are beautifully made and it is the smoothest and quietest exhaust system on the market, which is a plus if there are a lot of cops in your area.

 

thanks Bob




one more question.
how can i tell if it's JDM or USDM mugen?

if i was to get used mugen what should i be looking out for?

hey get that setup, I'm runnin the exact thing on my car right now

 

i want to dude, but i want to make sure there is nothing wrong with it first.


this guy is got a JDM R engine swap and he's got all mugens. he wants to sell me he's mugen's so i'm wondering what i should be looking for when buying a used setup.

also how do it get it cleaned up?

any idea?

 

If you are going to spend $2000 for an exhaust system I'd go with a real 2.5" system like SMSP or HyTech. The Mugen header performed the worst in the great header test, it's pretty much just a JDM ITR 4-1 and DC JDM 4-1 which you can buy for under $300. The Mugen exhaust is 60.5mm, 2.38" the same size as every other aftermarket exhaust out there. Neither their header or exhaust is anything special besides the twin-loop muffler. HyTech's twin-loop is even cheaper than the Mugen and uses larger piping. It's better to be informed than just buy from a big name brand thinking it's the best.

I don't know why Mugen uses a smaller 2.38" exhaust with their 2.5" header. My guess is it was NOT a performance decision, they just wanted it to bolt to the stock cat. If you have a nice big 2.5" collector the rational thing would be to match it with a 2.5" cat and exhaust for the best flow.

USDM headers have a 2.0" collector by the way.

The mugen header Im currrently running(and selling) is the USDM, 2.25 collector. Dynoed that with AEM intake at 178. Not sure how much difference there actually is with a 2.5 collector. Just thought Id let you know.

 

Just to give you a visual, the difference between the JDM and USDM collectors. Thanks to Tuan for this one.

 

thanks guys.
i would love to get some HyTech or SMSP's
but it would take 10 years before i can get them to my door man

hey i was also thinking toda header & type one or toda with buddyclub?? any idea?

i know it's going to be loud. >_<

btw any body has pics and links of the complete HyTech & SMSP setup's?
