1.5 TSi - engine mods - intake / exhaust etc

Collect my estate this morning

Already got wheels and suspension lined up, but would like to do a few more bits to it

I have the 1.5 TSi 150bhp Manual FWD

I’m looking at a remap by a local tuner who’s very good with VAG stuff

Debating an intake, possibly the MST kit as it’s the most enclosed system

But not sure what to do about the exhaust on it

Wasn’t sure if a resonator delete would gain much sound

Or would I need a custom exhaust somewhere

I don’t mind if the exhaust tips aren’t visible

But I don’t want anything that sounds rubbish

Tried to do as much research as possible but struggling to find the info I need

Any help would be amazing! Especially with photos
