Does anyone whether there will be any big differences or chnages, good or bad, if i put a performance petrol exhaust/back box on my diesel fiesta??? If this is either damaging or wont work does anyone know anyone or anywhere where i could get a back box for a diesel engine?? its non-turbo.

Won't make the slightest bit of difference to performance sorry

 

wel not in performance department maybe, but in terms of the loudness.sound of the exhaust? this if i fit a back box (rage for example) and it is designed for a petrol engined car and i fit it on my diesel engined car. will the noise be different from the noise that it would have made on the petrol car? also, what kind of noise would it make? it would be lower noise than a petrol as diesels dont rev as much?

no, same noise! noise depends on make of exhaust!

 

I suspect it will still sound like a tractor although perhaps slightly louder

 

Damn tracotrs lol!
Well cheerz 4 ur help guys, will have to do some more ringing around exhaust workshops and investigating and find out what i can do with the damn tractor.

No prob

 

eh,... surely if its on say a 2l petrol astra, the noise of the exhaust would be different to a diesel engine car, even if it had the same exhaust,....
