HKS hi-power or AP exhaust

is one better than the other, performance wise?
i know exhaust dont make that much of a difference
but maybe a single side exhaust constricts more airflow compared to dual?

and will a HKS hi power fit with a Agency Power midpipe?

it's up to personal preference on that one....if you would rather have duals or single.

with the single, it won't weigh as much at least.
the ap has sweet looking ti tips....so...take your pick, it's up to you

the ap midpipe should bolt to the hks catback

so theres basically no power difference?

i heard someone say that single side has more low torque
gain cause less airflow or something like that..

anyone know anything about the differences in power
between single and dual?

The only thing I can input is

The HKS has a 2.95 piping and 3.8 Tip~ Single

The AP has 3 inch piping and a 4 inch Tip - Dual

Very tough pick I would purely base my decision on whether I wanted an empty hole on one side of my rear or have 2 Tips.

Then there is the whole weight difference.

The HKS weighs 34lbs without mid pipe.

The AP weights about 55lbs with mid pipe.

And I would say the mid pipe ways anywhere from 8-12lbs

Decisions Decisions...

nope.

bogging could be a lot of things anywhere from a dirty MAF sensor to a clogged cat.
