I heard that they can sometimes have problems scraping the ground, so should I get 4-1 or 4-2-1?.......and also the welding I heard was not done well and can fall apart, am I right???......please vouck for what I heard, are they even worth it?

 

megan only makes 4-2-1 for the h23, unless you've got some "custom" order one. ive heard good things about megan headers/exhausts as far as construction goes...

 

on the h23 it makes good power vs price. theres a thread on here about a guy making like 10 hp off it. search for it

 

yup that was me.
mine broke though because i bottomed out denting the secondaries, putting a hole in the flex pipe, and breaking the flange and the hangar.
only bad thing is that the hangar breaks easily and the gaskets it comes with suck.
i heard megan now makes them with 2.5inch collectors instead of 2.25inch which is what i got.

 

doesnt the megan header go through the flexpipe and to the catalytic converter???......I want to make sure of this because I have a hole in my flexpipe

 

Yes, yes it does

 

really, well thats good. does anyone have any pics of what it looks like installed on the car both the engine and underneath?

 

top shots






only under shot i got


other shots




dyno graph

blue is stock header and red and green are the megan header.

 

^^^^^ sorry that's supposed to be me. i posted that while on my brother's screen name.

 

so the before dyno was stock and the after dyno was with a megan header and no other mods? 11 whp gain is impressive, i remember seeing a prelude si awhile back in import tuner that gained 20 whp with I/H/E.

 

oh i missed that part. all the runs had an aem cold air intake and an hks sport catback exhaust and 17 inch wheels.

 

from import tuner june 04
1995 prelude se baseline 122.4 whp/124.8 trq
w/ aem cold-air intake, skunk2 catback and dc sports 4-2-1 header
134.1 hp, 135.2 trq

that engine responds very well to boltons, must be because its such a heavy breather, i am considering picking up a 92+ prelude si for my next project car, they seem like they are easier to find and a lot cheaper than 4th gen prelude vtecs

 

yeah, I got my 1994 prelude si for $4300 all stock and a little bit of rust on the driver's side shock mount and cruise control, and a little bit on the power steering lines, but she runs like a beauty, Iguess I just sacrificed looks for performance, but it was worth it, only 118,000 miles..........so the megan header looks like it has a flex pipe

also because all the stock components are really restrictive probably for emissions. a guy in my city has an h23 with stage 3 crower cams and he's pulling on all the h22 ludes here. if i wasn't turbocharging my h23 i'd probably do what that guy did or build an h23 vtec. the stroke is really good.

 

nice fugging gains... imagine what could happen with a 2.5 inch collector

i wish i did the collector mod but oh well... i'm going turbo now.
