Cats or no Cats ????

[GT stanger]

if I'm keeping my s-197 all natural, and really just looking for low end power, should i do a x pipe with cats or no cats?

IIRC removing the cats builds high RPM power but you loose power in the lower RPMS. If someone else could chime in.....

i would say not cats. If you are taking in enough air up front then opening up the back will result in a power gain. It must be tuned properly though

keep in mind it'll be very raspy.. i removed the cats before doing the full exhaust setup, & it was very raspy & load..

thats why im with cats in my full exhaust setup, & never been happier

I'd keep them.

I'd keep them, the benefit vs risk of fines, having to deal with emmissions, isn't worth it.

Go H pipe and no cats! I love mine and my stingers.

I ran longtubes & off-road H-pipe with factory catback on my 06 GT and LOVED it.

...(plenty of other videos on my profile was well)...

I will say this though... removing the cats on the 3V really makes them alot louder. If you have an aftermarket catback or plan on going to an aftermarket catback, then you may want to keep the cats. I eventually put on a Flowmaster catback with my longtubes & no-cat exhaust and it was OBNOXIOUS. I liked it much better with no cats & stock mufflers.

The way I saw it... no cats + stock mufflers = more power than cats + aftermarket mufflers.

no cats man it opens up you mufflers. and with the LTs ooooooooo sounds even better.

i went through 2 sets of Bassani cats in less then 6 months. Kept blowing them out. Boost added that though. If your staying lower hp. cats will be fine but if u want some higher hp, get rid of them.
