Hey,
I have a true dual flowmaster setup with headers. I want it to have some more rumble. Would I have any problems if I cut off the mufflers and put turn downs on (straight pipes)? Or put something louder on...no clue what series flowmasters.

I have heard that the more pipe the better...is this true?

Thanks

 

dump the pipe right after the muffler. dont put on any turndown. they make it quieter

 

I agree cut the tips off and just leave 4"s after the muffler. Will be much louder, also, do you have the 4 cat setup? if you do cut them out & put in 2 magnaflow high flow cats.
