4" Bolt on muffler for a Del Sol

I am thinking or replacing the stock muffler with a 4" Bolt On Stainless Steel Muffler.
The stock muffler tail pipe is 2 1/2 inch. The replacement is 4" dia tail pipe.

Any unintended consequenses I need to worry about?

Thanks.

Doesn't your fart-pipe's maker provide adapters?

Whatever you do, I'd advise saving the OEM muffler for later use: It costs
$500 new.

 

yup, there are unintended consequences. the reason factory doesn't
provide 4" pipe is that if the pipe is too big, flow becomes turbulent
and unclean. this can cause exhaust back pressure, and thus, lower
performance.

its the old conundrum: do you try to look good for when the other guy
passes you, or not allow the guy to see what you're driving because he
can't get close enough?

 

He apparently envies farting along.
