gotgasracing said:I just removed the cats from my stock exhaust and MAN does that thinng sound nice...!!! I haven´t received anything but good comments on the throaty sound on my car. Everything was left stock, just swapped cats with straight piping. Perfomance wise it made a whole difference. At quarter mile my personal best time was 14.470, after cats swappped -- 13.670. In my opinion this mod mad a huge difference. I really recomend doing it!!!

I agree.. It's more likely that you learned to drive alot better. Without a tune, you actually lost power in the low end. You may have gained a bit up top, but not almost a second's worth in the 1/4. That 14 something is very high for these cars. With a good driver off the showroom floor, they will run 13.8 and even lower.WallDiver77 said:TELL me again: YOu picked up .8 of a second by eliminating the cats only! NO other mods......Correct?!!!! Right after I took delievery I swapped the stock mufflers for some MagnaFlows and discovered it made no detectable difference. Ok..... it sounded better, but did not perform any better. I have been looking for some stock exhaust flanges so that I could make up a replacable bybass for my cats. Haven't found any yet......... need to find someone that has installed headers that no longer needs them so that I can try this.

Did you happen to record the conditions on these runs? Being late november now, I would have to imagine you were running in cold dry air, and the previous run was in hot humid air in the summer. Without a record of the conditions during the runs, those numbers are worthless.gotgasracing said:At quarter mile my personal best time was 14.470, after cats swappped -- 13.670.

I ordered my Pypes O/R h-pipe from Brenspeed to go with my SLPs, but the sad part is that I hafta wait until March to put it on. But go under thier media section and listen to the clip of the Pypes O/R h-pipe and SLPs - I think I'm going to get in even more trouble with the local police for my car being too loud!!Black2006GT said:By the way, which pipe did you use? I am checking out Bassini and Pypes brands.

gotgasracing said:yes that will probably be true, if you live in the US and have 98 octane fuel minimum..... fuel down here in mexico is 94 octane at the most
Besides, it doesnt matter if you lost a few on the low end.... My intentions are to be on the high end when at the drag strip!
