Exhaust flanges

plastic orange · February 17, 2017

Exhaust has been blowing for a short time at the flanges at the cats, so I'm off to Pipe Dynamics in Leven to get them replaced. The chap I spoke to said he's done loads of these on LS400's and it will cost £150 including vat - I'll report back when it's done.

Good luck, fingers crossed they fix her up without any issues.

Powerflow replaced y pipe with S/S welded direct to both Cats and centre box for £200 as per a thread on this forum and others have had the same thing done (quoting the forum thread) at the same cost.

I got mine done near Ipswich and very pleased with outcome. Took about three hours.

You may want to check out the thread if you are not commited. "Rotten flanges to Cats" I think was the title?

Flanges replaced in stainless today in about 3.5 hours and car now silent again - £150 all in. However, I have to agree that the original stainless possibly isn't up to the standard of the modern highly polished stuff as it certainly looked pretty rusty and you can get a magnet to stick to it (shouldn't with stainless). However, the system has lasted 18 years and will be good for a long time yet.

On another note, it turns out the the local Lexus with the loud exhaust I'd looked at with thoughts of buying had It's noise produced at Pipe Dynamics. 2 visits - 1 to get rear silencers removed and replaced with straight stainless pipe, and then back again as it wasn't loud enough to get the middle silencer removed. So it as I thought - a straight through system and american hotrod loud. The fitter told me that you won't get a loud rumble from a bmw v8 with same mods.

I'll try and post pics later.
