If you want the engine to be less asthmatic then a stainless cat-back system is the way to go. Removing the secondary (middle) silencer will of course result in a louder exhaust note, particularly if you're then tempted to go for a nice big shiny tailpipe or two but you will notice the difference in response and fuel consumption.
I'm saving up to have my 2.5 done at my local people (Redhill Classics) but they've already done my Mk1 Outlander. Performance is much livelier now and I reckon I'm getting a 7 - 10% increase in mpg depending on what sort of driving I do. It also now sounds like the EVO it always wanted to be!

Moreover I didn't want to change my very rusted line any more that's why I've opted for an everlasting one (fingers crossed!), or at least lasting as long as the car itself (fingers crossed once more!). But I don't understand why you say that the original system is better when you've changed 3 times out of 4 for a SS one...

Living overseas, I'd no other choice to get another good one for a decent price. Would I be tempted to ask in France for a custom made one, not sure I would find somebody keen to do it, or even so it would be awfully expensive. Thank you for your experience report. I hope a little mpg improvement as well: that is the main purpose of the swap. Hope springs eternal...

If the original system had still been fitted, I would have taken time to carefully remove any grotty steel from the outer sarcophagus, and weld in new metal. One may question why this is preferable to a stainless system, quite simply the difference in noise levels between an OEM system , and an aftermarket mild steel, or stainless system are like chalk and cheese Brian |

I like my stainless from Tony Banks, but then my old one was half rotten original, half rotten aftermarket, so I had to do something! It doesn't seem much more noisy on tick over or tootling along, but when I accelerate it definitely growls more, which I'm sad to say I rather like heheheh

I like the stainless one on my gold diesel - No silencers at all.

MIJ Exhaust stainless steel
Here it is & well fitted:
Unlike what I may have read here & there, this SS exhaust delivers a mild and soft roar when idle. And driving from the cosy interior I've been hardly able to tell the difference between the old metal one & the new SS. But today I didn't go up more than 3k revs! I'm relieved: I'd feared it might be too noisy... I'm a happy bunny! EDIT: http://arnaud.aurejac.free.fr/Rover/SSexhaust.mp3

Looks good fitted.
To answer your previous reply, no I wouldn't buy a new car with dents and scratches and I would have been miffed myself if a nice shiny exhaust turned up at my house damaged. I'm after one for my MG ZT-T but I want a single exit pipe, large oval. Plus a sporty sounding one, I know I should act my age but life is for living.

Thank you for that.
As far as I'm aware of MIJ Exhausts are doing a large quantity of different SS cat back & lines: just have a try typing "MIJ Exhausts" on Youtube... And they're doing sporty ones as well. BTW I haven't got any shares in that venture... unfortunately!
