have a look see what you think, this is a 3.2 system so i dont know what youll actually get for a 2.5, but with twin tail pipe box it was 311 sobs. About 100 each for the 3 sections on trade club. A single pipe box was said to be about 50 sobs iirc. To me, the options are 3 fold now if this is what vx are punting out.
1.standard vx, presume youll get similar. 250 on tc? Link below.
2. Aftermarket job for about 90 sobs(?) as james cdx has maybe he ll post some pics?
3. Custom made stainless guaranteed for life,as Albatross and Sp.32 have, might be a good idea to have one of those made with an extra lambda socket at the back for when the precat issue lights up your dash. Iirc about 400?? I "imagine" that might be a bit of a gamble if you dont like the noise it makes? But Sp.32s sounded ok at the rolling road day last Sunday.
I suppose it depends how flush you are and how long you want to keep the car. Pays your money, makes your choice...
