Why update the exhaust? Probably too allow more airflow

due to more airintake, but I must admit, I do not fight

for the last hp, and I don't think the airintake has gone up that much, even with the K&N-filter installed.

The exhaust, or the size / diameter of the exhaust seems to be the same for all the V70-models, at least I guess, there is no big difference between the 200hp and the 250hp versions.

Do you think the 50hp more will be a problem ?

I know that some people installed a second exhaust pipe to

increase airflow, but as far as I know, this is done to reach more

than 300hp.

Did not think about the second pipe yet, although there is already

a place / removable cap to install it, at the other side of the bumper.

Do you know where to get it?

But what does the catalytic converter have to do with that,

as it always stays the same?

The shifting problems are not really problems yet,

it occurs very rarely, but nevertheless thanks for the tip.
