exhaust options.
ok...im looking to open up the exhaust on my f250 5.4 sd.
ive heard various things like "opening the exhaust drops low end torque" and such...
ok, here are my plans.....
a gibson swept side exhaust
http://www.stylinconcepts.com/part.a.../categoryid/28
and this performance y-pipe
http://cgi.ebay.com/ebaymotors/00-04...QQcmdZViewItem
along with a high flow cat.
will that give me gains in hp and torque, or losses in one or both categories?
i would have posted in the exhaust forum...but there doesnt seem to be too much activity in that area....

Catalytic converters have come along way sence the 80's. The cat you have now is decent and could probably flow as much as a normal muffler. I have a gibson single exit, the sound is ok, but no real performance loss or gain. It's mostly for sound. I have been too lazy to get my truck to the muffler shop to build a better Y pipe, so I can't say what that will give you. Hopefully it will not tick under your/my feet under acceleration.

There's flowmaster, magnaflow, walker/dynomax, borla, b&b tri flow, corner shop specials, house brand, hedman, and flex pipe to name afew. You will not see a seat of the pants difference between any of them. So pick the one that you think sounds the best.

Bro,
you can get the same thing done at a local muffler shop
on a side note you will not get 33hp from that y pipe
I have a flowmaster 40 with 3" in and dual 2.5 out
as far as sound i was excited at first but now i want something with more rumble....i didn't feel or see any change other than noise

the y pipe you have has the same problems as the older v10's and kits can be had to repair that problem. flow master has a y pipe adapter many v10 owners have used.plus stans and some one on ebay have them.
take this ? down into the v10 area and ask them for the part numbers.
your 5.4 will have a much better sound, just don't look for huge gains in power.

You could always do what I did....straight pipes. In all honesty...not too loud. Stock manifolds (for now), stock y-pipe into single stock cat. From there, a single 2 3/4" pipe that y's into two 2 1/2" pipes to ss magnaflo pencil tips. I get a lot of attention. Not sure if it will pass inspection, though 
. My buddie's shop did the work.
Good luck. J.J.
