exhaust power difference?

[ocbaud]

how much difference is there in power between say a magnaflow catback system, and just welding in some magnaflow mufflers(what i have done)??

i'm wanting to redo my exhaust with longtubes and new midpipe and need to decide if i should get a catback system or use that money towards other stuff.

Depending on your area for what you will be spending a new set
of mufflers and a mechanic/exhaust shop to cut the old mufflers
off and weld the new mufflers on you might as we'll just buy the
whole catback.I just got a Magnaflow Magnapack catback one
week ago belive me it's worth it. Magnaflow=Quality

i've already got an offroad Hpipe and weld in magnaflow muffers. i'm wondering if i would see any increase in power by going to a full cat back

Going with the larger diameter of piping 21/2"
with 31/2" tips your exhaust will have less backpressure and will
let your engine breath easier.The difference will probably be 1 or 2
rwhp from your weld in's.In my opnion the Magnaflow tips are alot nicer
than the tips on the stock catback.

ditto. i've got 3" rolled magnaflow tips now and i love them

Also by changing the tips it will a little better.

I think the hp increase would be VERY small

So small as in zero?

 

[loosescrew79]

So small as in zero?

How could the hp gain be zero with a larger diameter c/b. Wouldn't that mean more free flowing air exiting the motor? which could result in a very small gain

And yes the a larger set of tips with change the exhaust tone.

 

[myponyrocks]

if you take away too much back pressure your car goes slower.....

Exhaust tips have minimal effect on anything other than sound. And even then its debatable.

 

[Stang|ess]

Doesn't make a difference in sound either.

 

[loosescrew79]

I had a truck and now have my stang that had a sound change from nothing more than a tip change

 

[Stang|ess]

All in your head. You have a screw loose, or perhaps 79 of them.

 

[loosescrew79]

No there is only 3 screws in my head and they must be tight. I have yet to hear any rattles

IMO on a mildly modified car 2 1/2 pipe is kind of a trade off. It moves the power band a bit. more peak hp but proabably a little less low end.

the more mods you add the more the 2 1/2 pipe will help. If no heads, cams, and or blower is in your future I would spend the money elsewhere.
