back box

[edwardospeako]

does anyone know if you change a backbox from a 120 vti to a thp twin back box appart from looking sweet would it alter the sound of the exhaust??

As far as I'm aware the pipe before it is identical, you might have some trouble with the diffuser though, I'm not sure if the two are the same.

As far as connecting it goes, should be a saw off-weld on job.

120vti and THP are different tube size.
THP are quiet anyways with stock exhaust.
Remus do a twin outlet backbox that fits all models, comes with all the necessary reducers and sleeves, also has templates to trim the rear defuser.
They sound great too!

Thanks guys I don't think il be getting a Remus just because of warranty cover want to be safe with a genuine citroen part although I'd love a Remus one ha

If you change your exhaust- its only the exhaust part of the warranty that would be void so I was told
In fact- I am doing the turbo a favour by having a bigger diameter (63mm) exhaust on, with a sports catalytic converter- less back pressure on the turbo and smoother flow for emissions gotta be better than standard

You could make such an arguement for a remap as well mate, sadly I think Citroen will always take a dim view on most mods....

[edwardospeako]

Yeah I know it's rubbish how you can't mod them well you can but you know what I mean ha

Eh? A remap adds no pressure on the engine? BHP up, Torque up! heat up?

They cant write off a warranty on the paintwork for a remap for example

i guess a remap would nullify the warranty on the engine. Engine £8k, Exhaust £300

[lfcrule1972]

£8k for an engine ??? Is that what they cost ??

Is yours gold plated Chris ?? No wait it will be chrome won't it ? lol !

What I meant was that remaps can improve fuel economy so improve how the car runs but it would still invalidate the warranty

[Chris_Blue]

Just guessing LOL , bet not far off supply and fit

even a remap with economy virtues, will be tinkering with engine components maximum and minimum capabilties- so it may help the economy, and knacker the engine. remaps are no-no's for warrantys

Yes they are. For my racing a vanilla engine would have been 8500 euros.
