I'm no one? I just said (in the post directly above yours) that I run the RB muffler. It doesn't seem restrictive, has held up for about 5 months with no problems, and sounds good.

 

how loud will my exhaust be if i replace the cats and put in a straight pipe..my car is completely stock, sadly enough.

 

How do you tell someone how loud their car will be, with any given change?

 

I'm using a Spintech XL in conjunction with an RB presilencer and a large diameter/very short "resonator" originally meant for a Grand Marquis. The resonator is between the presilencer and the Spintech. I'm happy with this combo. It's deep toned, none of that "bees in a can" stuff. That said, without the resonator, it's a whole 'nother story, unacceptably loud and high pitched. For that matter, I've tried different combos of these components and this is the only setup that I'm 100% pleased with. The resonator does take 7hp (167 vs 160) but I've made it easily removable via flanging it's installation so it's easily replaced with a straight pipe in 5 minutes.
