He would make more $ form me going 2” so I figure he must know something

What do ya think?

Thx LukeZen

The blokes at best mufflers weren't even able to supply me with the right extractors for my motor, in fact they think a B16A is actually called a D16A (no not the D16A8;))

ouch

thats not good :rolleyes:

How good are the tuned length 4-1 for sohc vtec headers tanghy sells?

No brand
mugen replicas

A lot more cash but maybe there worth it?

Thx Luke

when u get headers,..4-1 may not be the necessary best one to go
it flows better but you do lose low end for top end....4-2-1 is more expensive i think but they do give a overall better performance.

They work more effectively with an air filter fitted, and of course it chews a little more gas. I had mine fitted at Liverpool exhausts.

jords car goes hard. nothing wrong with his setup!

a set of 4-1 extractors will give better top end power but often result in some low end loss. 4-2-1 will give a broader spread in the power band but wont give as much top end gain. so basically 4-2-1 is more suited for everyday driving. it sounds like the guys at best mufflers dont know squat. if your going with extractors you have to replace the rest of the pipe or it will just bottle neck and the extractors wont do shite. 2" is fine. no way is it too big - if those guys reckon thats too big for a car which is raced, i'd say they are racing in their driveway. some peeps go with 2.25" piping as it can give slightly better top end, though often with slight losses in bottom end power and torque. really have to decide based on how you like to drive.
