Err, I'm not sure any induction kit can make something sound like a TVR! It's a lovely roar though, snaps heads as you flaw it past pedestrians... even people who clearly don't care for cars will turn and look to see what the racket is.
With regards to fitting. All I can say is I'm an absolute clem when it comes to anything mechanical, I couldn't and wouldn't dare change the oil, or anything on the car, the bravest I'll go to is taking a wheel off. And I fitted this kit in around an hour, it's just plug and play.
