So after a few months of enquiring about after market exhausts, watching YouTube clips and generally not liking the sound of z4s after having performance back box's installed (apart from the seriously expensive units) as I find they sound raspy and not grunty if there is such a word, which is definatly not what I'm after.
My brothers 350z sounds insane, and I know it's not a z4 but I wanted something deep, and this is where I heard lewisdavid's z4 with a straight pipe no back box and it's very very good. Unfortunately every exhaust company I went to will not perform such a job so I purchased some 2.25mm pipe and my friend is cutting my back box off and welding the straight pipes on at weekend.
I can't wait.
Has anyone got any vids of straight pipes?
Thanks
