i have recently got rid of the egr and replaced the middle silencer with a straight pipe, whilst performance is better it does drone on a bit inside but my motor is a 90 hardtop so yours may be quieter with the carpets and seats
egr bypassed,center box replaced with straight pipe, sounds nice outside can drone on abit inside [ bit like the mrs ] turbo seems to spool up quicker,td5alive remap next on the agenda:D
