no opinons here....no hear say, no "my friend" stuff....just REAL responses from REAL ppl running it

i have a built, 2.1L and am needing to get rid of my 60mm catback....and i'm just trying to see what gains ppl make with 3" over 2.5

 

depends on if your runnign turbo or all motor mostly.

A 3" on a turbo will let it breath much better and you will see much better gains in horsepower.

I have had both 3" and 2.5" on my car and i only saw about a 3 wheel horsepower increase over 2.5" and that wasn't even all the time. Depending on the day/weather and what not, sometimes the 2.5 put down more hp.

Get a really good header, maybe hytech if you have the money, and go with whatever it cheapest in terms of exhaust.

 

i've allready got a good header, better than hytech.....so that's no biggie. price isn't really a big deal either....i want what's BEST, not cheapest

i'm n/a...

 

this IS the na forum.....so one may assume he wasnt talking about turbo.

id think about running 3" on a really built 1.8+ high compression motor.

 

I'm running a 3" Thermal cat back on my B20VTEC... no problem even with a stock B16A head.

enlighten me please, whats better than hytech?

 

there's a lot of stuff better than hytech

and better is NOT just power, there's a lot of aspects

i run an an-r with a merge, and i WHOLE HEARTDLY back it on being better than a hytech. the ONLY issue is with cracking, but that was taken care of with a flex joint.

i'll be testing a new, custom, RMF header soon...that i will put money on being the best now


sure hytech is nice, but the price and wait is just STUPID. also, the whole power thing is kinda overrated when it comes to headers. 1-2whp at any point on the board is NOT worth $1200+ and when it comes to the fact that i've seen it out powered by an AN-R on different occasions makes it even less of a choice for me. i really think that hytech has really come down to being a bandwagon.....everyone looks at the name and thinks " damn.....there's a baller, i better buy one." personally, i'm ONLY interested in power, fitment, and reliability...and i've found all 3 of those in my header, for less than half the price, with half the wait.

RMF is AN-R

Randy Monroe Fabrications

The "R" in AN-R is also Randy. just an FYI. There is no difference in the design principles of either header.

no hate man, just curious

for most of the big name builders, depending on what coast they are on, most would jump on the hytech/smsp "bandwagon".
now the hytech not making much more than the AN-R, i would love to see some back to back comparisons. but your looking at a header that randy made for you, to order, with no options, against a header that is made for you, with tons of options, and they even take engine size/mods into account. your right, they are 2 different ballparks according to price, and IMO very deserving of it.

dont think im bashing, im just stating my opinon, much like you did yours. and my opinion is based on real world experience; i.e. i have seen 2 an-r's, both looked good, both were mild steel, and both had lower quality welds and piping IMO to the hytech, and smsp that i have seen.

if anyone can get back to back hytech/smsp/an-r comparison up, i would LOVE to see a cheaper header kill these big boys!

I owe that to our conversation the other night.

 

jeff from IB posted in his forum that smsp destoryed both hytech and an-r. i don't know if he has any dyno charts....but based on his past experience...his statements seem trustworthy....maybe i could find fyno charts comparing the three..or even two...here it is

http://www.importreview.com/fo...ber=1

he also wrote in there somewhere that he tested an-r with smsp and smsp beat it as well.

in my personal opinion...i'd be happy with any of the three.

 

I agree that you should only need a 3" if you're running a lot of power that needs to get out and that would have to do with running a very built motor. My friend is running 3" on his Nissan 200sx, he has a VE swap and he got 7 whp from going from 2.5" to 3".

 

Everybody talks about hp gains from bigger exhaust, that makes sense. I'd like to see a dyno that proves that torque doesn't go down though.

Trust me, Rob knows all about where Steve Brown's design principles come from. However, it does not make them equal to a header that comes directly from Randy himself.

 

Thats true. I have a header that came directly from Randy himself and I have also seen AN-R stuff and Bisimoto stuff in personl. There is not perceptible difference. Randy taught his methods well to others.

 

Actually, I was saying there IS a difference.

 

I know what you were saying. I was just disagreeing with you. The difference is not huge. Nothing that would effect power. Just longetivity of the header. Randy has better welds.

 

if i get one from RMF, it wont be a shelf header.............

 

the experiance that i had on the dyno with 2 headers and 2 exhaust i have determined that i am better off witha headertech header nad a 3 inch. i saw huge increases in tourge going to open header from a 2.5 inch tanabe on my setup.

basicll y i say go as big as you can as long as you can deal witht he noise. my car is way way loud.

 

Randy also has back-purged welds as an option, which flow a little better.

you MIGHT lose a LITTLE on bottom end...but who cares?!?!? this is a honda...it doesn't do **** until 4k anyways. i'll sacrifice some useless power for useful power any day
