Fitting a Roush Exhaust

[andrewr]

I want to fit a Roush Exhaust to my M400.

I am trying to decide if I should get Roush or Plans to fit the exhaust. They are quoting 6 hours for the job.

Has anyone on here fitted one and have a 'blow by blow' guide and a view on the possible problems.My car is an early M400 with 5k miles and looks like it has never been wet, although it msut have been.

I have done a lot of mechanical work, have a good toolkit, but need to fit the exhaust with the cars back wheels on top of a couple of breeze blocks each side.

I will also update the fuel pump, loom and intercooler. Once all complete I will Roush to map the car.

Thanks in anticipation

Regards
Andrew

ALso, should I wrap the manifolds and fit turbo blankets to the Turbos to control the heat in addition to the ceramic coating on the Roush exhaust.

Roush - Do it.

get a couple of good axel stands, get the back clam off, intercooler off and you'll have no problems fitting it, not that bad a job to be honest compared to some i've done on the car.

You can always buy one of these to help you out, the lift, not the car.

how much is a Roush exhaust if you fit it yourself ?

[MadMacMcMad]

I fitted mine. And to be honest once the old one was off, it was very easy. Get yourself a grinder as the old bolts can be a bitch.

Also, this is a job for a pit or car lift.IMHO.
Lot safer too.

Do not attempt to assemble off the car. Fit it piece by piece from the turbos to the back.

Thanks all for your comments.

Any comments on the lagging and turbo blankets, Necessary?

I would be interested in this.
Would we then be able to get shot of the silly metal heat deflectors? They make everything else difficult.

I had the ceramic coating and have had no heat issues since fitting.

I have now collected my exhaust.

The pipework and cats are all ceramic coated.

I am going to fit in the next couple of weeks. Do I need to wrap the front of the exhaust, or is the fact that it is ceramic coated enough to control the heat.

The exhaust cost me £1800 + VAT (complete with two new CATs). No sure where the £2500 comes from that people talk about, may be that includes fitting.

Thanks for your help with this

You don't need to wrap ceramic coated pipes.
£2500 included fitting and re-map and a pair of straight through cat replacement pipes (as well as the cats)on my M400.

I'd wrap the bit closest to the Battery or turn the battery around.

Even though you don't need to wrap it, it sounds much better inside the car if you do, the wrap kills any ringing in the exhaust.

If you look at it like this : Lotus charge £1000+vat per standard V8 cat, and they are crap and fall to bits, so £2500 for the exhaust, cats and re-map looks cheap be comparison.

Adrian/Nicky,

How much of the exhaust should I wrap, just the pipes and cats or the entire system?

Any recomendations of which wrap to use, how much to buy, what fixing methods and where to buy?

Thanks
Andrew
