For clarity here are some pictures of the new MILLTEK non-resonated centre section (removes the central silencer from the MILLTEK system). This sounds much better than the standard Milltek system which uses a large central silencer and gives the 1M the exhaust note it needs! The car now sounds similar to an Nissan RB26 engine in a GTR Skyline R32/33/34
MILLTEK full primary-cat back exhaust system WITH CENTRE SILENCER next to the OE 1M BMW exhaust system:
The MILLTEK Centre silencer & secondary cat-bypass pipes (looking forward to the engine)
Our NEW MILLTEK Non-Resonated (centre silencer removed) centre section & secondary cat-bypass pipes (looking forward to the engine)
As you can see this new MILLTEK section simply removes the central MILLTEK silenced section and replaces it with a non-resonsated pipe.
We have a number of these on their way to us now so please PM if you're interested in making your 1M Milltek sound MUCH BETTER!
