i would rank the midpipe first as well. when i put my Dinan midpipe on it was a new car with all the added power. the diff would be second in my op. the other stuff is ok but nothing special. i have them except for the fuel and the only things that impressed me was the midpipe and the diff.

but again the diff is not for everyone as you noted. although i have yet to read anyone with the diff that does not like it

-Increase redline

Some might argue for a high flow air filter but I'm not convinced these actually add power.

With these mods you can count on 30-35 hp gain for about $6k. This car will leave any FD ratio modded stock M3 in the dust.
