Just putting the feelers out to your knowledgable ppl, about upgrading the exhaust on my 328i coupe.
The Car has had the nikasil block replaced (now alusil ?), and has had the M50 manifold/throttle body conversion plus a K&N filter on housed in a nice carbon fibre housing
The bloke I bought it from said the conversion had been done by previous owner who was admin on some M3 forum, and was done really well, but he didnt mention a remap (although my local bmw indy took it for a spin after inspection2 and said he believed it had been remapped from the way it performed).
So, I have been thinking about the next step for tuning, and maybe an exhaust would be a decent performance gain for the money ?
Any advice ppl please ?
I'm not looking for a loud noise, if it stayed like the standard one I have I would be happy, am just looking for BHP gains. Any help on what is the popular choices for my car would be appreciated, I have looked at a few (on google) and they all just quote 'really nice loud sporty sound' etc and nothing about the BHP gains, hence my enquiery here for you lads & lasses opinions / experience
