The cat's will rob some of the power compared to resonators. The resonators would have been cheaper, and lower the db level while not at WOT considerably.
I decided to go with the cats over the resonators cause they were smaller and easier to source. The cats i got are small and pretty much seethru as they aren't really restrictive :P. the filter inside is pretty much just directing airflow, reducing drone n rasp. i agree resonators would be better but i felt cats would be a safer route. i also dont have such a strong offroad smell which is a bonus. With the cats the stang is still pulling like crazy so its all good
Gotten the cats or resonators installed yet? Would love to hear what it sounds like with them on.
Hey Rockaholic, yeh i installed the cats this weekend and they have improved it alot. Its still loud but the rasp and drone is pretty much gone. there is a area between 3200 and 3400 were i get a little bit of rasp but it lasts for like a second and after that it goes away and is just power loud :P . The car is a little quieter at idle but sounds just like some of the GT's ive seen with full headers and hi flow cats, and thats without the ghost cams.
The cats are really high quality, and at 60$ a piece they weren't a bad deal. they have corrected all the problems i was having and i am "legal" now :P... I got them to cut the x-pipe and weld the cats in since that was easiest place to mount them. after the x-pipe the stock pipe is squashed flat and is not perfectly round from the factory so that would have been more of a pain to install. Plus now the cats are in the general area where troopers look so i should be "more legal" :P
I will have another video soon so you can hear it. i haven't had time to make one yet since college is getting hectic as its finals week for summer class.
I can say that im happy with the system now and just wanna drive it around :p, in the end the cats havent hurt it, they've refined it
