So I researched, watched dozens of videos and saved. This wasn't an easy purchase for me. Sure, the others like the Invidia R400 were cheaper. The others had the titanium tip. But this one had the sound I wanted, and ZERO drone!!!! She's subdued when you're staying off the throttle and want to have a conversation with your passengers. She turns everyone's head when you punch it. I'm so glad I spent the extra money and got a superior catback system. Don't waste your money on the cheaper ones as you'll regret not saving a bit longer and being completely satisfied.
