ok so for a gs-r i was planing on getting some edelbrock headers but i dont know which kind i've searched up on honda-tech but all the pictures are dead and it doesnt say which kind.. and also alot of people say get the importbuilder mod? whats that? how much does it cost and where can i get it? any pictures?

 

It's header...edelbrock may not be the place to go for an import header either...they make a good header, but i'd say look around. It depends what your doing with your exhaust system as a whole. What exhausts are your looking at (if any)?

 

kinda leaning towards the ApexiN1

 

i believe the n1 is 2.36" piping...there's a bottleneck right there if u get the edelbrock.

 

i have the edlebrock header and there ain't no bottleneck anywhere.

 

what about this "import builder mod" or whatever for it

the edelbrock is 2.5" piping genious. If he goes from 2.5" from the header to 2.36" in the exhaust that is what we call a bottleneck.

so what. there's a reason people have 3 inch collectors and go to 2 1/2 inch exhausts or even less.

you're not always going to go by the collector to mate the exhaust.

lol, you are retarded. So you are promoting bottlenecks... And people who have 3 inch collecters probably don't need 3 inches. They made the mistake of buying a header with a 3 inch collecter in the first place.

Who's retarded here??

The Edelbrock header is a 1.75" primaries with 2.2" secondaries, with the stock cat outlet which isn't any larger than 2.25".

Where do you get that its 2.5" piping? The IB mod header has a 2.5" outlet for use with a JDM cat.

 

I read that it was 2.5" piping. And going from 2.5" into 2.36" is a bottleneck...

Its not 2.5"!!! Learn the facts, and where ever you read that, its wrong

So no, its not a bottleneck! If you don't know, don't act like you know!

I just went a measured one, and its actually a 2" secondaries and a 2.125" outlet.

 

roger knows his ****. dont argue w/ him

Not sure I want to know a lot about smelly brown stuff!

Oh, and the Edelbrock header does make more power than a DC sports 4-2-1 header, 3whp more.

Did you also know, that you can have smaller piping in the cat-back than the header outlet?? As the exhaust gasses cool, the air gets more dense the further away from the engine you go. So there wont be a bottleneck.

yes, what i was saying earlier.

 

2.5 Inches cat-back. Nothing smaller.....every Honda has to be boosted sometime or another in its life.



BTW, Marauder is all bark and no bite HAHAHA.


EDIT: For claification, I know the topic is headers and bottle necks It's already covered and I felt like ******* around. Internet communciation sucks!

Thx you Marauder..

i've read alot on honda-tech that is u get Edelbroke headers its best to run IB mod for more power out of it?

 

It depends on your setup, if you are worried about emissions and want to use the stock cat, that no, don't modify the collector. If you want to run an upgrade cat, like a JDM or other 2.5" cat or test pipe, then I would get the IB modded 2.5" collector.
