: Questions about 2005 STS performance parts

04-24-13, 06:39 PM
I recently got a 2005 v6 STS.

I would like to get a cold air intake for it but I can only find universal fits but I would prefer something specifically for the V6 STS.

I am also unsure as to what lowering kit I should go with.

Does anyone have the D3 springs, and are they hard to install??

Also I can't find an exhaust kit for the V6.

Any suggestions would be much appreciated, thanks!

Aftermarket won't breathe any better than OEM, but it's your car. Volant sp?

Exhaust - same.

Overall, it might be fun and sound cool but Cadillac didn't leave much for tuners.

I have a 2005 STS aswell but it's a V8 so far put a volant cold air intake and corsa exhaust. They sound sweet and feel a bit more power nothing huge though. Not sure if they would fit on the v6 just google like sts v6 volant most sites said if the part would fit or not

Volant makes a CAI for the 3.6 specifically. Won't add much, just makes more noise.

For the 3.6 poke around in the first gen CTS forum, same engine, much more aftermarket talk there.

But by all means, enjoy!
