That nissan must have like 5 ft/lbs of torque with that big of an exhaust or is he fooling us and really has the powertrain from a peterbilt?

Okay i have a 2000 Focus SE and i just put a Flowmaster catback exhaust on the other day. At first it was kinda quiet but then i let the gas run out and put 93 grade gasoline in. It sounds a whole lot better but the downside is when i rev; the RPM's drop down and theres low popping or grumbling sound like a Honda with a 3.5 inch exhaust smh. My friend told me that i may be running rich; because i do have a huge problem with gas and i need to replace my plugs because the maintenance of this car wasn't done entirely before i bought it earlier this year. What by this what do you think my prob is?

what else could i do to boost performance after this. I also installed a Steeda CAI.
im trying to get to at least 250hp by this upcoming summer.

yea thats what i have on my focus. it sounds great. you just have to let the existing gas run out then fill it with like 93 that's what i did. but it just pops at the end of rev's
(rev)....(gurgle pop)
