If I was to go nitro, could I run on unleaded gas in my car and then when I decide to race pop in a octaine booster? How well does this work and how much of the stuff do you need? also is 2.5in cat back limiting a 50 shot + of nitro? Thanks

The 2.5" exhaust is ideal for the nitrous setup.

For a 50-80 shot, you will need to run at least 93 octane. You can use an octane booster if you'd like to do your best to avoid detonation. Just make sure it's for use with nitrous oxide, some boosters aren't.
