Just had a Cobra cat back with Y pipe fitted today that I picked up on eBay for £350.
And wow has it transformed the car, nice burble on start up. Normal driving you hardly notice it's there but when you plant your foot the noise is just sublime and not too loud.
when using the rev match it's just music to my ears.
Exactly what I wanted as I use my 370z daily, I was worried it might be too loud but I Highly recommend a Cobra to anyone.
My only gripe is this is how the car should of sounded coming out of the factory.
I didn't realise when I recommend the invidia you were getting your cobra for that price
I agree at that price it's a great deal
Enjoy
