I read a while back about the possibility of JBA releasing some 1 3/4 long tubes. I want to pull the trigger on long tubes, but only want to do this once. Maybe I am looking to much into this and the difference isn't worth the wait going from 1 5/8 to 1 3/4.

Thanks for any insight.

Not sure if you will be able to tell a difference, but it would be something new that not many people have. I just installed my JBA 1 5/8 last weekend. Like others say regularly, as long as you ditch the stock manifolds and do a good solid tune, its a win.

A little birdie dropped a hint at me this morning that I thought would be really cool if you have the coin....Nissan - Exhaust - Headers | aFe POWER


I'd really like to see these gems on Titans in the future. The joining construction of the collector and intermediate pipes is different from the norm...its good....really good

unless you have better cams, head work, more cubes, or blower, you will not capitalize on the larger volume...

more air in = more air out.

your typical everyday mods will be just fine with the 1 5/8.

Exactly ^. The standard 15/8" JBA is the way to go unless your boosted and or cammed. JBA is coming out with these just not sure of a release date. Cajun will have them for sure.

"This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.

All aFe headers and extension pipes are engineered and manufactured in our Corona, California manufacturing facility"


These two sentences from the description on the aFe page are funny to me. You can't legally buy or use them in California, but they are made there!
