I just got my 2006 cobalt SS about a month ago and I just recently found out that the person before me had a Flowmaster Exhaust put in it. I was just curious as to how this will affect my horsepower and torque! Like I know stock is 205wph and 200lbs--torque, but what should it be around now that I have a flowmaster exhaust?
Thanks for the help!

No way to tell, every car is different. The average HP dno'd on our cars is 210whp. If I had to guesstimate, I would put you between 210-215.

for some stock cars i've seen even 215-217hp so you can never tell.

Some yes, all no. Average being 210ish. I agree with you though.

Ight So I can expect anywhere in between 215 and 220ish with the flowmaster?
Like just alone how much does would a flowmaster increase a car's horsepower?
I'm sorry I'm new to this whole modi'n and rac'n bit, I read as much as I can about the car.

i had a 40 series muffler on my 2005 ss/sc. i did notice a little bit of difference when after the install which also including 2.5" tubing from downpipe back. but once i put in the xtc header and downpipe it made the muffler sound like ****. it was so loud and raspy that it just sounded annoying. hopefully urs will sound good if do a downpipe and header

its a terrible muffler for the cobalt, i ran one for a year and switched to Dynomax.

how is it a terrible muffler for the cobalt ss/sc?? i have 1 and it sounds nice and beefy and i feel the power difference in the high rpm's and not to mention the backfiring now...sounds sweet...but i also did a 2.5 inch resonator instead of restricting it again...

trust me if u get ride of the cat a flowmaster will start to sound horrible. they belong on v8s plain and simple

I'm sorry I have a quick question.. This is way off topic but I gotta ask. How do you guys get those signatures with your names engraved within the signature. That's a bad ass sig. Hispano1
