MOD NAME: Golf Tee Mod

MOD COST: FREE, $0.00

MOD BENEFIT: More low rpm 'rumble' exhaust note.

MOD DESCRIPTION: Remove vacuum line that closes a metal 'butterfly' valve. plug removed vacuum line with a golf tee or similar.

In the picture below you will see a metal butterfly valve in the right exhaust pipe, immediately above this is a rubber hose that connects to it. Nothing needs to be done on the exhaust side, as it will just stay open now.


This is the rubber hose that you pulled off of the exhaust, you can see I plugged the hose with a wire crimp.

Wow, I'm so glad I read this. Turns out my butterfly valve was so covered in soot it was NEVER opening! I had to jab it with a screw driver to get it to move rumble=

Mine is stuck closed too. How hard did you have to jab it? I don't want to break anything. Did you have to disconnect the vacuum hose first?

So is mine, I tried hitting it with a screw driver and hammer, but it just bent it open a little. I don't know how to get it all the way opened.

MOD COST: ~$10.00

MOD BENEFIT: Cleans out your motor.

MOD DESCRIPTION: Sea Foam Engine Cleaner

The picture below is from the link below, basically, slowly pour about a third of the sea foam into the vacuum line indicated below. Turn off the car, re connect the vacuum tube, pour another third into your gas tank, wait 10 min, fire your car up and rev it up. It will blow out crap from inside your motor.


*Note* my car threw 3 codes after I did this, they were all related to fuel mixture and such, so I went to autozone to have them read & cleared. Couple months later and its all good!

Not really a mod, it helps clean out your engine of deposits, but i wouldnt recommend doing it on a car unless it has 175,000+ miles and was poorly maintained. Sea foam corrodes your fuel lines and can really mess with your engine if done too much. My friend sea foamed his S4 every 500 miles, and boom goes the dynamite, RIP S4.

175k miles is definitely NOT when you want to be treating your car with this Seafoam. Gunk built up in an abused motor is one of the only things keeping it from burning 1qt of oil every 500 miles.

That said, a well maintained motor will benefit from this treatment. More specifically, the M54/S54 engines should only be Seafoamed through the brake booster and gas tank. The additives in our synthetic oil are actually very good at what they do, and adding it to the crankcase is not necessary.

Show me evidence that this petroleum based product corrodes fuel lines. Your buddy's S4 went "boom" because its an Audi.

Mod name: debadge

Mod cost: free

Mod benefit: looks good

Mod description: use credit card and slide underneath each letter or number, removing the "badge" then use goo gone or alcahol wipes to remove the remaining gunk, whatever you use to take off the gunk wipe it off as soon as your done using it because its probably not that great for you paint.

Thin fishing line is also good to use to take the old badges off with.

Dental floss works good also. Clay bar to remove excess residue, or adhesive remover spray. Either works great. Then wax/polish the affected area to ensure that the water beads even and not in the shape of the old lettering.

Mod - Painted Reflectors
Mod Benefit - cleaner looking appearance
Cost - about $10 total for paint, primer and clear.
Difficulty - Easy, just takes time.

Painting the stock front and rear bumper refelctors vs. paying close to $100 for a set (front and back, or $60 for fronts).

I used Metailic Silver for mine. Did three coats of primer, 4 coats of color and 3 coats of clear. Not an exact match, but pretty close. The more Zanio (polish as they are now painted as well) I put on them with the rest of the car, the closer they match.

Nice thread keep it coming. I'm painting Kidney grills and pillars for less than $10, sandpaper, matte black bumper paint, and primer. I may also re-paint the mirror housing.
