As above £300 fitted I will even include a set of my exhaust tips. I have this modified for a friend who no longer has a z4. If you want a fruity sounding exhaust without the drone this is for you.

I have it advertised elsewhere also I am in ox28 so you would need to get to me for fitting. Or I can post if required.
My little blue zed is in lots of bits. With lots of things started and not many finished! I may have found the limits of my time and ability!!

Hi, have just acquired a very clean low miles (32,000) N52 2007 drophead. Could do with some better sounds, it's a 2.5, will this work? Any pics? Feel free to DM me Thanks. PS am also looking for a new roof motor if you know anyone, needs relocating too, the last one replaced five years ago according to bills! Think they would have learnt about the drain holes! Oh and also after a new spoiler break light, the existing one is cracked and half falling off!

It’s noticeably louder but far from offensive. It is not just louder it really improves the tone and you will get over run pops and crackles with sharp throttle lift.

Hi I've just read this again and seen the mention of getting over-run pops and crackles which I don't really want, just a slightly more throaty sporty exhaust sound. I don't think I can take any more snap crackle and pops I hsar enough of them from fiery modern numbers which really don't need them but just come as I see it as beacons to the boys in blue, gone are my days of wanted particularly get noticed more than I have to, I've even got a baseball cap on when the lid is down even though I am a tad folically challenged, I vudss I am just protecting from the sun.

So the question is, can this be more low end throaty without the crackles and pops?

I know I've got your WhatsApp link and video, that was very welcome and showed three cars side by side but not under load at speed, just static. I hope this message finds you well, I've been thinking about what I want. So is this a back delete or is your system adaptable or do you do another one to suit?

Hi Scott the pops and bangs are by no means like what you hear on hot hatches they are artificial mapped to over fuel and create them. It’s only with sharp let off of the throttle it happens. It’s defiantly not a back box delete and yes it will be a deeper sportier sound and I can also make a little bit quieter.

The only thing I can say is if you buy it and don’t like it. Your old exhaust will fit back on. And you could resell this one.
