Ls430 Back Box Help.

[Anuj]

Hi guys

Our 04 ls430 needs two new backboxes.

It's just turned over 100k, I was wondering if anybody has any recommendations on custom ones, because of course we want to keep the car quiet,

A bit of extra noise on acceleration would be ok, but the general idle etc must be quiet,

Are there any options? Or just stick with A lexus one, I have priced it up and a s/s custom one, the same size and shape as genuine lex is around 1/2 the price of the genuine one,

Thanks guys

a stainless system will last you,......................... defectively, Lexus produced the 430 with mild steel boxes I believe ......... shoddy !!

I would go for the s/s one.

Cheers matey,

Can't believe lex want nearly 1k to do the job,

Pipeworx in burscough said £175 each, or £200 and they will cut the boxes open and replicate the same design,

Needs a new shock absorber too but it's air suspension so not having any luck with that!

And an a/c leak under body

OMG financial catastrophe looms ............. stick to the Ls400 !

Nah, I much prefer my mk1 sport gs

We were gunna replace the Ls but the p/ex price on it was a kick in the ...

Full lex history etc mots by lex

Same tyres as when it left the factory genuine brakes etc well looked after, and what a ride, just a shame it's starting to age a bit now, but ah well. I've driven a 60 reg s350 and can honestly say the ls drove better.

I recently had a full SS sytem stuck on my 430, including 2 new catalytic converters for £600 made to measure.

Lexus would had charged over £1500 for this lot and then add the labour fee.

Had it done by Tony Banks in Leeds, i can give you the phone and address if you need

How does it compare to the standard set up matey? Noise wise

It is little noisier than the quiet Lexus setup, not like a subaru racket though, v8 burble i would call it.

There is a week spot on the back boxes that can easily be repaired with a small patch welded on and you will have a lot of life left in them.

Cheers mate

But I took it to my mechanic as he was going to patch it, and when he took the boxes off he said the top of both of them were literally shot.. And he coulsnt repair them, same with a local welders, because the casing around the actual box aswell

As anyone tried to marry the ls400 back box to the 430 system is it that different? would solve the problem and be a lot cheaper there are plenty of second hand 400 back boxes about.

finally getting somewhere now, rang a bespoke place, he said hes done them b4, and its a massive job to get right,

otherwise you get a droning noise,

Price £650 and 3 weeks notice to get box fabricated

any way rang lexus, and with all the loyalty discounts etc, got both boxes down to £431 all in,
find out from mechanic how much to fit too, but cant see it being £400 that lexus want!!!

to be honest in the interest of keeping the car quite and original thats not an extortionatley massive outlay - a set of dunlops will set you back about £600 on a good day
