Default BBK Longtube/Y Combo and cats...Questions
Emissions are strict in Maine, and unfortunately I need cats for inspection. Is there enough clearance to weld in some 2.5" Hi-Flow cats to the Y pipe? Does anyone know if the BBK Longtubes have 4 O2 sensor bungs (for pre and post cat flow)?

Also, looking online at cats, anyone ever deal with these before? Great product and insanely low price!!

"Flowmonster" is their name..

Thunderbolt.

Any opinions?

I have had thunder bolt and the magna spun cats. Both worked good with no problems and killed ALL of the rasp even with my loudmouth and long tubes.
