Hi there My girlfriends mini had a problem the other day in which the exhaust fell off from the CAT back. It made a really good noise apart from the tailpipe dragging along the floor.

I thought about making a straight through pipe for my mini, from the cat out the back with no silencer which would make it mega loud.. But ILLEGAL as well so can't do it.

So i am on the look out for a better louder exhaust..
I have a fairly loud system already.. Its a standard down pipe for injection with a CAT link pipe (de-cat) then a Fletcher 2.75 bore i think. The chrome one..

It fairly loud.. But I want the exhaust to sound bit more raw.. Like its about to pop flames out the back.. Or its got a better cam etc.

What options do I have..

I thought about fitting an injection LCB to cat but get rid of cat till MOT. For bit extra power and hopefully noise..

Don't know what else I can do..

Help please

I am building a mini miglia look a like so ideally i want the raw similar to the mini sevens. I know most of that comes from the weber. But if anyone knows of the twin exhaust system similar to the Mini Miglias where i can get it that be great.

i have and spi, i would say full straight stainless all the way through and the same back box the guys video had on i have the same back box, but as you say u want it to sound like its got power, and in my opinion you need to add power to the engine to give it that affect through the back box.

I agree its not just the exhaust that makes the sound, pistons, heads and definatly cams, infact most things inside the engine make the sound not just the exhaust, im sorry to say it but your not going to get a mini seven or mig type sound from a standard spi engine, like i said earlier i have a sligtly "tuned/ modified" spi lump now and that sounds very different to how my old engine in that video sounds, if you want a raw racey sound your going to need some money and some other parts for your engine, to sound powerful it will need to be well.. powerful, + webbers (or any carbs) help with the sound haha.



failing that get a cheap cherry bomb... LOL

Ive got a injections lcb on mine with a straight through pipe to backbox with the playmini twin one exhaust either side jobby in round rolled tips.

sounds AMAZING..... never heard anyone elses sound like mine. reallly deep and V8esque on Idle and when you give it the beans it sounds like a cross between a scooby and an anti air craft gun un the run down!!
