Will these work on a non-borla cutout ???

 

The borla plate should work providing that your cutout is the same size as the plates. The only problem that I forsee is that since the plate is not sandwiched between two steel flanges like in the borla setup, it may bend or warp. Not that this is a big problem it on a cutout. But If I were you i'd just get a chunk of sheet metal and drill or puch a hole in it to the desired size, then cut it down to fit on your cutout, drill your holes to bolt it up. Then just put it on. BTW let me know if this works out for you i'll write it down somewhere and keep it in my bag of exhaust tricks.

 

Well I already have the 4 borla plates... might as well use them =0p

 

it will probably sound like a bad exhaust leak under your car
