To replace the centre section of the exhaust, do you need any gaskets / seals?
Want to make sure I've got everything first

cheers

 

you'll just need the gasket at the join of the centre/back box, the tapered seal at the front should be re-usable....
Other than that, it's four bolts, and about 10 mins with the car on a jack..... or even two wheels on the pavement if you have no ramps/jack!

 

cheers
