Hi all you have guessed it I am a petrol head. From the past I have owned loads off Honda including civic type r dc5 crx and a few more also had a few Nissan including skyline gtst. I got into modifying cars from my first car and modified the gtst hard. Iam a very proud owner of a BMW m4 2018 competion pack. I need help and advice. It's my first bmw and I would like to take her to just over 500 bhp and 525 pounds of tourque. What do you suggest. Also is the exhaust system on the m4 with competion pack different to a normal M4.
Her is what I had in mind
Downpipe
Mid pipes
Full induction kit.
Stage 1 or stage 2 remap.
The main reason I've come on her is to see if any one knows due to competiion pack do I need to change mid pipe on exuest. Many thanks

For that amount of power all you need is a JB4 - simple - no need to modify the exhaust

If you're a petrol head, and love modifying cars, then the stock exhaust wont be loud enough lol, even on the Comp pack

Even driving around every where in sport plus to gain the pops and cracks, still isn't enough!

Litchfield Motors now offer proper OBD tuning for the M3 /M4. It gives 515hp for £720.00 or more if you start changing the exhaust. Have a look on their site. Just remember your M4 has the ability to record any "overboost" so warranty claims could be an issue if anything fails.

"For those customers looking for a more complete solution we also offer a fully re-calibrated ECU, providing a significant increase in power and torque. The software includes the latest BMW factory advances on models like the CS and GTS as well as including the additional burbles on the over run in Sport mode. This customised ECU mapping releases considerably more power than the tuning box and allows us to create a really smooth, driveable car. The ECU can now be tuned using the OBD port which offers fast programming or reverting back to standard"
