It is 3" with 3.5" tips - with no mods, not sure if 3" is any better than 2.5". Bigger is not always better.

We've been doing some testing on a 3" MAC. The customer said he had to learn how to launch the car all over again cause of the decrease low end power. So now the trade off, he gain 4 mph in the 1/4 and close to .4 qucker. Is it worth it? My vote is yes! Plus now we added a off-raod x pipe. The car sounds downright mean now. We also added a 6lb lower pulley this week. Will be testing at Cecil county Friday night.
