Ken is absolutely correct!

Here you go:




'TWC' means 'Three Way Catalyst'

I don't think £1700 even includes the manifolds/front cats, does it?

There are 4 pieces in total....two front sections, left and right, one middle section and the rear section.  Four cats in total and three boxes.  Total price for a replacement would be £3k+.   I know as my exhaust holed in front of the middle section box.  Looking at the exhaust on a ramp it had been patched up a good times so I decided to replace.  Thankfully the warranty that I had, 3 months, was going to cover it.  The Lexus guys and the garage were of the same parent company - Arnold Clarks.  The Lexus dealer did a full costing - £3150 that included everything.  I got them to pay for a full stainless steel cat back system as it came with a lifetime guarantee and sounds better and as a lot cheaper for them!

I still have a second hand centre section as I bought that thinking that it would be a fall back if the selling garage didn't play ball but thankfully they did.

The centre pipe split had been causing me problems for the last year (yes an OEM repair is £3-4k and no even with a lifetime cover). I was flux repaired a few times (£50 in total). I explored whole quiet "OEM" sounding SS replacements - quotes were between £650-£1500. However Longlife Birmingham reckoned the rest of system was unless I wanted a full system a partial replacement would suffice, the owner is also a petrolhead, extremley knowledge and highly recommended on the Korean car clubs.

The corrodded sections have been cut out and replaced for £150 with a lifetime warranty.

Here are some pictures prior to the repair.
