I just got a chance to install my gutted cat-converter today. It was a PITA to get the bolts off, even with air tools. After the cat was installed, I noticed that my turbo seems to spool up a little quicker; the exhaust got just a bit louder (more rumble); acceleration on the freeway seems to be quicker.

When I punch it, sometimes I get a "pop" (after burn) from the exhaust. For you guys with a straight pipe or gutted cat, does this happen to you? Just curious.

I get afterburn all the time and I am not even turboed but I have a gutted cat.

I always got realllyy nasty afterburn before, tuned the cam gears and it ran a lot better, not nearly as much flames and backfires... I know its cool and all to shoot flames, but i'd rahter not ;-) The police here dont take too kindly to my car anyways after registering at my uncles house, so they cant rag me on not having a muffler, cat, o2 sensors, evap system, egr, etc.. anymore...
