Thanks for your replies. I'll give it a shot. Yeah, my SR5 is pretty nice, if your interested, sometime mid january next year I'll be installin a 2.5'' straight exhaust from where the cat. converter is ( but that's going away

) to a htc performance muffler, custom mandrel bent 2.5'' exhaust tubing, pretty cheap. I could post some pics in the corolla section when it's done if anyone would care to see.
