Sorry to bring this back to life but if i have an 08 car with no visible tailpipes how do i attach the twin exit diffuser ? I thought the blank peice thats on now would just unclip but its part of the bumper, if i cut it out i cant see how the new diffuser would attach as there would be no clips to hold it in place

 

Loko ... I no longer have the Saab but I think I can help. The diffuser fits over the rear bumper. You'll need to the rear bumper to match the round cutouts in the diffuser. You can use an exacto blade for this. The bottom of the diffuser has holes which match up with holes in the rear bumper. The upper half of the diffuser needs to be adhesed to the bumper. I would suggest the marine-grade Gorilla epoxy, which is made to hold even when wet. You'll want to use plastic or nylon bolts and nuts at the bottom. I'm assuming your UK winters have salty roads like we have in the Mid-Atlantic region of the US.

 

sorry to sound stupid but i,m still not getting this ;oops:;oops:;oops:

this is how the car looks now, blank diffuser section is attached to the bumper and cant be unclipped

this is what i want to fit

so are you saying the new part is glued over the top of the blank diffuser and i cut 2 holes in the old section to enable the tailpipes to stick through?

 

You're not taking that part off. Take those 2 red reflectors off, they pop on and off so do it carefully. Then you're going to cut 2 round holes in that silver bumper so the diffuser can attach ON TOP of your bumper.

 

There's a bit more cutting than just the 2 exhaust holes, I did this on my '08 a couple of months back. You also have to cut out a portion in the existing bumper behind the red reflectors, and cut slots along the top for the locking tabs of the new diffuser to fit in. It's an intricate and tedious process of cut it and check it, cut it and check it. And an exacto knife is really not the best tool to use as its really tough plastic, and one slip and u get a booboo like dummy me. I used a dremel with a rasp bit.

 

Ahhh I get it now, thanks very much for your help ;ol;

 

Do you guys think a 3" dual exhaust would look good coming out of a 2.0T silver bumper? Like if I didn't get the diffuser. I like the other post of a pretty facelift but I'm not sure how the larger tips would look. I'll probably do a Photoshop and post it here.

 

I have 3.5" tips on mine, they fill the holes in the "diffuser" rather nicely.

 

I have Magnaflow 3" oval tips (with the Hirsch diffuser) on mine and I get complimented ALL the time on them!

See for yourself and tell me what you think?

That looks awesome. Making me wanna dish out for the Hirsch diffuser. I did a quick Photoshop of the 3" through the stock silver 2.0T bumper and it looked like it was missing a rear diffuser tbh. Not gonna even bother posting it.

 

I have it sorted now, a local bodyshop is doing it for me so i.m sure they will have all the right tools for the job, mines actually an 06 car but i.m going for the facelift look after finding an unmarked 2009 rear bumper on ebay for £50

 

Hi,

Does anyone know the type of screws that hold the diffuser in place on the 2008 up aeros ?
Trying to replace the aero diffuser with the hirsch one and just cant manage to get the screws off, its like a 3 slit screw with a bolt behind it.

 

Most of the factory lower diffuser mounting points, are done with plastic rivets and need to be drilled out. After I removed mine I used short stainless steel flathead self drilling screws in the factory holes.
