Anyone removed their cats from an 09-10 f150 and have good results from it? Just curious

 

Why would you want to do that? It's not going to make it run any better and it's going to throw a constant CEL.

 

Im not, I was just wondering if anyone has and what their results were. Im just interested more in the sound than the performance.. when i try to make it louder with straight pipes it sounds terrible..I like my flowmaster sound, its just not very loud on these trucks

 

Change your Flowmaster to a quality Borla, and get longtube headers with the STOCK cats which are a very hi-flow unit as is, and hardly volume killing at all. Running no cats with a custom tune works, but is it really healthy for those around you on a cold start? Longtubes, and a direct flow muffler, and long length and diameter tips will improve your volume.

 

do it man, my mpg jumped up another 20 to 42 mpg in the city, and it is louder then anything on the road, do it...

 

Love your first 2 posts..........jerk
