#1 should I get it with Eisenmann Connecting Pipes or not?
----if with Connecting Pipes, will it fit if I add AA Signature X Pipe & Connecting Pipes Later?

Without the connecting pipes you are left with cutting the ones off your factory exhaust. All connecting pipes were made to pair with OEM xpipe(akra aside) so yes it will fit with AA xpipe as they have stayed with the same fitment as oem.

#2 Is it ture that Eisenmann Race with X pipe(with or without cats) are too loud for drving around town?

Loudness is subjective. Some say the OEM exhaust mod is loud and others say the gintani race is quiet. I personally only heard the eisenmann race alone(not paired with anything) and think it sounds good but not loud.

#3 Both Eisenmann Race and Sport have the same performance gain right?

Should have the same performance gain(if any) just the difference in volume.

#4 what are the difference between with cats and without.

with cats no smell without cats(assuming your deleting the primaries) gains and smell.
