im looking for a site that has direct fits for your car. systems like magnaflow, flowmaster, dynomax, or other performance exhausts
I would go to each of those companies websites to check out their systems. You will get far more detailed information on the products and what they have available. From there you can shop different sites for best price.
vermiculite is goldish colored.perlite is white I wouldn't dry them out in the oven; i'd compost it and buy new stuff. they are very inexpensive
