Hooray!! Have now done my first mod to my m35 Stag. After a lot of people either telling me they can't get a dump pipe because nobody knows what the car is, or people just never getting back to me, I finally bit the bullet and paid the premium price that Ces racing charge to custom make my full 3 inch system. $2400 later, and i have to say, their claims of big power increases with their twin port dump pipe are well founded!
Haven't ran a dyno yet, but throttle response is MUCH quicker than before, turbo spools earlier and that gentle gforce push you get from the stock gear is much more of a shove back into the seat. Feels to me like about 20% more power at the wheels, maybe more.
If anybody in Brisbane is looking for an awesome power gain from standard, these are the guys. Pay the extra and get them to do it.
Next up, copgyback system. Anybody in Brissy area done it on their M35 yet? Help me!!!
