Hands down the best mod that I have ever done, and I have had quite a few mods done to my car.

Went over the RSS this morning, had the best experience I have ever had with a tuning company, had a tour of the whole facility, lots of eye candy to check out like a 959 in the back, bunch or cup cars, a stradale, so many things to see. Basically a one stop shop for almost everything.

Off the bat, huge difference in the way my car performs. Got on the toll road and opened up, had an Evo to play with then got blown away by a M5, but then again I only have a C2.

Great guys over at the shop, great showroom with all their products.

You guys will see once you come by and visit them. They are right in Costa Mesa, close to the Ferrari of Orange County.

Met the designer of the plenum as well. All I can say is that they are very knowlegdable about their products and very approachable for any questions.

 

Sounds sweet. Any dyno #s with the upgrade? You have a 3.4L too. They are getting good #s out of that engine. Im waitng for a 3.6L guy to speak up here, ANYBODY

 

Man, that plenum really sounds like a great mod especially for the 3.4 engines. Hopefully more 3.6 guys chime in on their experience. RSS really is a great company, I got my Cargraphic stuff from them extremely fast overseas from Germany!

 

Bump on the 3.6 results.
