catless doesn't stink if you are on E85.

We see gains generally of around 25rwhp with most long tubes. To be honest most headers perform very similarly and the 2" does have a slight advantage but you pay in fitment. If you are going to do the install yourself you'll be glad you spend some extra cash on a big name brand header. If you let us do it go ahead and save your money. We'll deal with the fitment issues.

Yep...if your tune is on point. Anybody that says otherwise needs to go back through their tune.

And it's nothing like having no cats on pump gas.

E85 smells a lot cleaner after being burnt. We can always tell after a car runs on the dyno if it's gas or ethanol. The weird thing is to me is how bad the raw Ethanol smells. If you spill any during fill ups you might as well start your whole day over.

I was always hoping E85 would smell similar to the way methanol does, but unfortunately it dosent. To me it still is pretty bad on E85 although not as bad as regular gas.

Make sure your exhaust is 100% sealed with no leaks at all and the tune is nailed down. That being said I’d always run cats for a car I drive on the street because of ice bergs
