I cant remember where but did someone install the rear diffuser by taking off the lower panel and then putting a fine bead of gorilla glue on the top lip of the diffuser and place under the bumper where typically you would drill holes to attach it.

Then copious amounts of masking tape to hold it in position and 24 hours later voila - a fully secure diffuser.

The only problem is that it cannot be removed without destroying the diffuser. Something that does not bother me since I will leave it on even if I sell it.

The benefit of this versus removing the bumper seems to be a better approach but wondering who did it or who suggested it and how they got on with it?

 

Just been doing some googling and this product comes in very highly recommended.

I would never do this. Not only would I be concerned about the glue not being strong enough to hold the diffuser in place at speed, but then there is the issue that it would not be removable as you said. You need to remove the diffuser to get to remove the muffler. If I bought a car used from someone, decided to put an aftermarket exhaust, and I could not remove the diffuser because somebody had used glue to attach it, I would be pretty pissed. Do the job right.

 

Just been on a Yamaha R1 forum and someone there used gorilla glue or its generic name polyurethane adhesive to secure a special visor on his motorbike front panel. He had the bike for 3 years and did the other side of 150 mph on many occasions had no problem with the special visor. So I guess thats good testiment for the use of the glue. Also the glue is often used in windscreen placement to secure the outer edge to the car body so that the windscreen adds to the structural integrity of the car. So as far as not being strong enough I am pretty sure it would be ok.

I did not know that to remove the rear exhaust you need to remove the diffuser. Hmmmmm.. This could scupper my plans after all. Unless I left the exhaust and sold the car on with the exhaust and ofcourse the warning that the diffuser in glued in place...

 

and what if someone gave you a gentle "love-tap" from behind (it's been known to happen)....hate to imagine the mess it would create

but if you do decide to go this route, please keep us updated.

 

Why not install it the way it was meant to be installed? Removing the bumper isn't a giant deal in the grand scheme of things.

Here's when I did mine:

 

BTW you might need to remove the bumper no matter what. There are a couple of bolts that hold the two middle parking sensor brackets that are underneath the bumper.

 

Yes agreed any car accident hitting my Aston anywhere would leave a mess.

 

Karl I got to hand it to you. Your skills whether its reupholstry or body panels etc are very good. I dont quite have your skills or the bravery. Good work all round.

 

Agreed. This is a hack, and one reason I absolutely detest buying cars and motorcycles from people that say "I work on my own cars". It demonstrates incompetency and laziness, and makes me absolutely bonkers. I used to be a professional mechanic many years ago, and the goal when you fix or repair something is to do it as good as the factory did - or better.

When I repair something, I will always follow that creed. If I break something during a repair I get a new part, never kludge it. If I have to join to wires together i will properly solder them and shrink wrap the joint rather than using a tap-a-line, for example, or run an entire new wire of the correct color and size if at all possible. And I almost never do non-reversible modifications, especially on premium vehicles.

I have been known to pass on buying used cars / bikes when I see hack jobs, I don't want any part of them.

 

^^^^^ BTW Duane, "I work on my own cars".
