New exhaust - should I try DIY?

Hi all
Just received a new exhaust for the 360 from Nuvolari. Havent even opened the packaging yet.

Half of me is saying dont even open it. Bring it to your specialist and let him fit it.

The other half (the child half) is saying give it a go, how hard can it be?

Any one ever fitted a new exhaust to their 360? Is it something a complete novice could do over a beer or 2? (calling 575er!) Or should I go straight to the specialist?

Ferrari's: 360 Modena, 550 Maranello
Ex's: Dino 308 GT4, 612 Scaglietti
The Rest: Rolls Royce Silver Shadow, Porsche 911 2.7s, Porsche 911 3.2 Carerra, Ducati 916... and the Land Rovers

Q. Does it scare you to take the rear bumper/fender off the car?

It really is a must to remove the old boat anchor out. Once you fit a smaller aftermarket unit its often possible to do it without this step.

Its not really a hard job but some of the old nuts may be very rusty and hard to remove (quitw often snapping the bolt - so no going back then! . Seriously, if its in the garage and you take your time it really isn't difficult. Now that all the workshop manuals are online its easy to see exactly what steps are required too.

Don't forget to isolate the battery (turn off power completely to battery with front compartment battery isolation switch) before restarting the car. The ignition computers will attempt to re-learn (as best they can) the lower back pressure exhaust... Ideally a remap is in order but most people don't do it (and therefore loose a significant amount of the gains possible with a sports exhaust). Ferrari official race exhaust actually came with replacement ignition computers mapped specifically for the job (which gives you some idea that its really the recommended way).

Strive for perfection in everything we do. Take the best that exists and make it better.
When it does not exist, design it. Accept nothing nearly right or good enough.

Easy DIY mate. The order I do an exhaust swap is as follows:

- Remove grill
- Remove bumper
- Remove exhaust tips
- Loosen clamps on silencer/cat joints
- Prop up silencer on gearbox bracket (a block of wood works well - this is to stop the heavy silencer dropping down and stressing the cats and headers)
- Undo the bolts holding the "smiley" bracket to silencer and gearbox bracket, withdraw bracket
- Lift out silencer - this is easier typed than done. You need to wiggle it to slide it off the cats whilst tipping it forward to clear the hatch catch
- Loosen the bolts at the cat/header joints (this is to allow the cats to rotate)
- Fit the new silencer in place (Tubis usually need the smiley bracket turned upside down so it is actually smiling and not frowning)
- Leave the cats loose until the final position is known
- Fit the tips and then offer up the bumper to get the final position
- Once you're happy with the positioning tighten up the silencer brackets properly
- Rotate the cats by hand until you feel they are in their least stressed position. You will feel them tighten up and loosen as they are turned
- Once the cats are in the right place tighten up the cat/header joins before tightening up the cat/silencer joints
- Fire up the engine and check for gas leaks at all the joints
- Refit the bumper and grill

If you need new gaskets between the tips and silencer I have a load on the shelf - happy to post a pair out at cost.

Also, fit new all metal self locking nuts on the bolts holding the tips to the silencer - I have seen these get shaken off in the past (again, I have some on the shelf as well as new stainless bolts if you want them at cost).

If you get stuck at any point you can call me to talk through any issues.

Well I fitted my own front and rear challenge grills over a couple of nights (and Peroni's)
Though I imagine taking on an exhaust is a little more complex. I'd like to think i could do it, but something is telling me to be realistic and let the experts do what they do best.

Thank you Aldous. Now that I look at it, I think it was your instructions I followed when installing the challenge grills.

If you can fit some in, put painters tape in between the bumper and body. When you loosen the nuts up, the bumper sometimes pivots a little bit depending on how you're holding it. Probably won't scuff the paint, but it never hurts to be a little cautious.

It's also worth checking the body gaps before you remove the bumper. You can position it however you want on the way back in, but at least you know exactly where it was before you took it off. If you really want to get obsessive, mark some pieces of painters tape on the bumper with a marker so you have some reference lines.
