Yesterday I went to a custom exhaust vendor to get my much delayed Turbo Exhaust custom made.
My objective was to have a free flowing exhaust to free up some more horses and to have a new look exhaust.
As I result we agreed on a 2.5" straight through system with two silencers and different tailpipes to provide some back pressure.
We started the car with no silencers and it was mega loud and I liked it but would not be able to live with it on a day to day basis.
The result is this:
2.5" ss with minimal bends. The big bulky thing you can see in the middle of the pic is the Differential. ( we will be talking about this later
And on the car:
Now the nightmare begins............
Drove home. The car felt different. quicker spooling and a little louder. Performance wise it felt quciker and more responsive. I am sure I have gained some ponies.
On the way home I heard a loud clanging noice from the rear of the car.
I thought **** the exhaust had fallen off.
Got out the car and had a look under the car it was fine!
Got in the car and drove it again and it did it again but got louder louder and then BANG....car would not move.
THE REAR DIFF HAD BLOWN!
Luckily the guys at MX5MAD showed true customer service and came out to the garage. There main mechanic said he would replace the diff there and then.
Another 5 hours later. the new diff was on.
Heres what we saw when we opened the broken rear diff:
As you can see some of the teeth on the clutch type LSD had broken clean off.
The bits you can see in the oil is metal bits!!!
Heres a big peace:
Now the good news:
I now have a Torsen rear diff. For those who don't know what that is. It is the strongest rear diff and is an LSD. So no excuses for not going on the 1/4 mile now! :wink:
The bad news:
I have a bill of £1000. Yes £1000. The more I dont want to spend anymore on my car...the more I end up spending.
However the rear end is now bullet proof. I hope!
I am happy the nightmare is now over.
I go to sleep!
