After getting the APR stage 1 tune i'm now considering a Milltek exhaust system, just trying to decide where to get it from and whether to get turbo back or cat back. The agents that supply Milltek in Sydney seem fairly expensive (from what i have seen so far although i'm still waiting to get a few quotes back).
I got a quote from a company in the UK (TSR Performance VW / Audi / Seat / Skoda - Performance Tuning ) and they were quoting the following:

Non res cat back with AEV = $1,307 (includes shipping to Oz)
without AEV = $1,017 (includes shipping to Oz)

Non res turbo back (cat back, down pipe & cat) with AEV = $2,324 (includes shipping to Oz)
without AEV = $2,034 (includes shipping to Oz)

I'd imagine i'd need to add another $200 for installation at Volksmuller or the like, but it still seems a fair bit cheaper than buying direct in Oz?

Just not sure whether i need AEV, and whether the full system is worth the extra $....any ideas what difference in performance a full system would give me? And is the AEV worth considering?

Has anyone used TSR in the UK before?

Cheers

Will
