4-2-1 headers, what brand is good at reasonable price??

[TODA AU]

FWIW, we fitted our headers & cat + 2nd hand mugen twin loop.
This was to a bone stock EK4 VtiR.
Starting power was 88kw @ wheels...
After fitting system... 98kw... (+10kw)
Not bad for a 1600cc engine.

Dynoed in shoot 4 - Std aribox, std ECU, ignition timing set factory 16deg.

Good guys to deal with,currently making a custom set of 4-2-1's for me atm to suit my build.(best of calling them,ask for Derek)

They are $$$,but as it has been said over and over "you get what you pay for"

how much?

what kind of sound difference do you get out of toda headers? im starting to steer towards this and a mugen twin-loop system =)

is there a more recommended exhaust system for toda?

and what is the best size for dc2 - 2.25" exhaust or 2.5"?

What do you mean by sound difference ?
The headers do give the engine a clean tight reving sound.
As opposed to a 4~1 stye system which sound more Subaru like...

For DC2 use 60mm ID or 2.5" OD exhaust system
FWIW, the Mugen twin loop system is very good.

thankyou for your information - very handy

i like a deep rumble sound kinda like the wrx, but i do want mid to top end power and sound isnt really important but wen ur spending this much money u want it to look, perform and sound good as long as the sound is deeper and not tinny than im happy =)

[TODA AU]

A tinny sound is more a product of the muffler than the header.
Eg: A DC5 with TODA headers has a deep smooth, muted note.
Change the cat back to a Fujitsubo Power Getter & it changes to a loud sharp blasting sound... Still clean & smooth, but very different.
Change again to say, a Buddy Club Spec 4, the note changes yet again.
It's higher pitches with a metalic ring in the exhaust..

This is all with no change to the header or cat.
But for a truley deep rumble, you'll need 4 into 1's...
Or something similar.
It may not give you the best power output, but you'll get the sound you want.

wow this is great information... iv been wanting to know this sort of stuff for a while.. its made me hesitant to buy

how different with the power will the 4-1 really be compared to 4-2-1? im looking for power in 2nd, 3rd, 4th gears and from about 4krpm to 9krpm

and what will the mugen twin-loop sound like? iv been looking at that and the tanabe super hyper medallion (or whatever its called)

Not at all...
Re-read the link given and actually read it...
Not just glance at the graphs.
A good 4~2~1 beats the JDM 4~1 every where.
A not so good one does not.

The Mugen exhaust gives a deep, clean, smooth note when used with TODA headers.
Re Tanabe - sorry, it's been a while since I've worked on a carwith one fitted so I can't remember to give comment.
