Seems like my car is really hurting with the 2.25'' Should I just disconnect and leave it open after the test pipe? Belevie it was answered before that it is safe for me to do this correct? Can't find my other thread.......
Get the ATP virtual exhaust system...problem solved. Install it right after the 3" dp or test pipe. Bypass the rest of the 2.25" exhaust system (btw, I don't think OEM exhaust is even 2.25"....i think it's more like 2").
Or, you can do what I did. Throw a Magnaflow straight-thru glass-pack right at the end of the downpipe...it muffles it enough so that you won't draw negative attention, but it's still loud enough, and mean sounding...and it's a straight through design and has little or no backpressure. And it costs only $16 or so!
