These flange kits fit perfectly and the clamp is very durable!! The flip style T-bolt quick release is awesome as well. I use them for a disconnect on the downpipe for compound kits, makes it very nice for removing the downpipe to work under the hood.

High quality, perfect fit

Very high quality they weld up very nicely and the fact it comes with a regular nut and lock nut is awesome!

Great quality, perfect fit! No exhaust ticks! High quality clamp, seals perfectly!

Bsi has top notched products at very reasonable prices. Recently bought some 4” vbands fit and finish is amazing only ones I will ever purchase again
