I’ve done a lot of modifications on a lot of cars over the years, and most of the time my satisfaction in these modifications range from satisfied to mildly (and occasionally very) disappointed. Not the case with the GT exhaust! This was my second major mod to my 2008 C30 R-Design (the first being factory Polestar tune). My Volvo guy was very impressed with the build quality of the GT exhaust. “This is no off the shelf exhaust” he said “Elevate really took their time to design this and manufactur it.” Okay, I was happy to hear that. He also noted that it was very easy to install. Immediately after install, I took the C30 for an hour and a half drive home. The exhaust note is perfect, you definitely know it’s there and there’s a nice bit of rumble, but yet it’s not overly obnoxius or droning. As others have said, this is how the C30 should have sounded from the factory. The GT exhaust is well worth the money, and you’re not only buying some performance, you’re buying smiles. Well done Elevate.
