Hi guys,

My 1998 1275 is playing the fun game of not really working again. This time it is reverting back to the issue of the exhaust falling off which has happened before. It has been ripped of at the y joint 2 or 3 times now and Im wondering the best way to get it sorted for good. It has apparently been raised by a mechanic before (although im not so sure it did anything) but is still horifically low, as can be seen in the attached pictures. The clamps at the y joint are as tight as they can go however the exhaust can still wiggle a bit. Im now thinking if it is actually possible to raise it and clamp it better to the downpipe or if it would just be better to go for a decent exhaust system like a maniflow which i've seen have been rated highly around here. I do like the sound of the current system (not sure what it is) so if there is something similar to that which actually stays on the car that would be great! Below is the link to some pictures of how it sits currently.

I'd suggest a complete new system but before buying I'd check to see if the catalytic converter is still whole internally.

You can get an MPI stage one kit that is basically what you have fitted already just nice and shiny

If it's already what i've got but a bit shinier, is there much point? Just thinking from a money stand point.

OK that is sounding more and more like the solution, is it worth getting the stage one kit or are there any other alternatives? I quite like the look of the twin centre pipes that sweep up slightly but also love the sound of the current system?

Maybe you miss my meaning. Just refit what you have correctly.

I would definitely go for the Maniflow LCB and centre exit DTM system and heavy duty fitting kit. If you like to hear it go for the single box option.

so go for this;

https://www.maniflow...56&product=1088

in conjunction with this;

https://www.maniflow...00&product=1247

and then this fitting kit;?

https://www.maniflow...ct&product=1224

 

Just a few questions, first, what is the difference between the second link and the larger/smaller pipe diameters here?;

https://www.maniflow...00&product=1243

https://www.maniflow...00&product=1251

Is it just the size of the exit pipes and just the bigger one being louder(?) and protruding slightly further out?

 

Second, for the 3/4" kit, is the difference between the DTM and non DTM just the sweep of the exhaust or are there some other differences?

 

Finally, is that kit linked just a simple bolt on? I just don't recognise some of the clamps!

 

Thanks again for the help

Maniflow's website is a nightmare to navigate but if you ring them they are quite helpful.

As your car is an injection model, I think you will need this:- https://www.maniflow...56&product=1361

as it has the fitting for the lamda sensor.

I also think that your car may have exhaust hangers rather than the rubber cotton reel mounts that most mini's have, so it would definitely be worth giving them a ring before ordering.

As for pipe diameters, most standards cars use the 1-3/4" up to around 80bhp. Above that use the 1-7/8" system. Although maniflow may advise you differently.

There's not usually a problem in fitting as I believe the 1-3/4" fits inside the 1-7/8 pipe.

1 3/4 is actually good for more than 100bhp

And will likely improve low end torque as well.

Ok thanks, Im in conversation with Andy at ML Motorsport to see if it's best for me to give it to him to sort it out but if not i'll definitely give them a ring for some help.
