exhaust question

[em1rida]

recently i swapped my stock muffler to a 4inch cannon
after the stockie snapped, i have an ek1

i was wondering becuase of this change will i lose some low-end power?
or would there be a gain?

you may loose low end power due to the loss of back pressure from the stock exhaust. Higher revs might be better thou as there is less restrictions in the exhaust.

Is there any noticeable difference now with your cannon?

shouldn't make any difference, just noise.

it may be minimal loses though if its only a cannon. if he had a full 4 inch exhaust from the header than thats a different story.

That is too big!!

[OMG.JAI xD]

Your cat will produce most of the back pressure.

If your cannon has a 4" inlet, that is just ridiculous.
But if youre talking about the whole cannon, its alright. It just amplifies the exhaust noise.

Really its a trick into thinking youve got a fast car cause it sounds more mean.

being a canon most likely its a 4" outlet. Nominal performance differece as the main restrictions being the crappy bends, cat & resonators are still there.
It will flow out slightly more as there is less muffling.
