Resonator delete IMHO is a cheap if slightly crude way to increase exhaust sound, cabin drone would be my main concern, especially under load up hills etc. Maybe okay if you don’t plan any further exhaust mods.
Add a dp or rear box at a later date and you’ll soon be digging out your resonator to refit.
I like the look and sound of the PP system, maybe not so much from inside the cabin. But listening outside when I got a friend to drive my car it does really does sound very good.
If I was to change any part of the exhaust system it would be the downpipe. BCS Powervalve in the UK make a great Downpipe with a 200 cell cat. No cel light even without a tune due to the mini 200 cell cat fitted to the oxygen port sensor. No TD1 as not part of the ECU and also good for up to 20-30 lbs more power.
Only snag is it’s a lot more money at £795 delivered.
