bigr1 -> ive got the belanger cat-back w/stock cats on my 93 and its LOUD. Although LOUD is a subjective issue, if you will be driving it a lot and you are concerned about noise, then Id go with either the stock cats or the high-flows. I couldnt even imagine driving my car w/o cats. After driving it now, my ears ring for awhile. btw, its even a tiny bit louder now with the hardtop on (i think the exhaust note is reverberating in the cabin). sounds great though
