straight pipe and no cat

[blk_shadow]

hey guys just a noob as question..
is there a purpose of having a straight pipe and no cat?
is der any gains?
or its just there for a sound?

straight pipe without cat is used to create better airflow without any restriction, therefore will create extra power. but again, it all depends on what you have done on the intake and header side of thing (or even internals).

its all about balance.

wouldnt balancing be the same as having the right inlet size for headers,cat muffler and other pipping?

how come other drivers can get away of having no cat and a straight pipe?

what I mean is 'balance' as in total balance between 'in' and 'out' (like intake header and exhaust for example) not 'balancing'

cos there are ways on playing around with the diameter of the pipings to create more power. or do it wrongly, reducing the power.
