hey guys..
Cut off my 5th cat and welded 2.5 inch pipe right after the last O^2 sensor.(no Check engine light)
That 2.5 inch pipe was then welded to my brothers old Aftermarket Cobra Muffler (2.5 inch)

It sounds like stock to me. Did you notice any lose in performance, 2.5 is a little big for 3.0, you probably lost some backpressure.

 

Like stock? no way dude.. haha.Stock was so so so restrictive... it seems to run the same.. no change.. if any it will help. a single 2.5 inch exhaust should be damn near perfect for it. i also have 3 inch intake. its not like true 2.5 dual or anything outrageous. it breathes very well. I dont think my truck is fast by any means what so ever. its slow. but for what it is ( a ranger with 150 hp)... it does pretty well.

 

Well since back pressure does nothing...


2.5" pipe is what every aftermarket cat back kit that I have seen uses.

 

There are no oxygen sensors after this converter so how would the obd2 know?

 

your driveshaft is a little rusty.....

 

Ya, that looks nasty!

 

The aftermarket exhaust systems i've seen i thought were 2.25..? but i'm not positive. and... well guys. it is metal... and i'll be honest and say i dont clean up the underneath of the truck all that often. haha. after 5-6 years it should be rusty..

 

what kind of muffler?

 

Lol if you guys get ruffled about that driveshaft rust then don't ever look under a vehicle in the northeast! especially mine

 

i dont like it not loud enough for my taste and did you chirp 2nd and 3rd?

 

look at a new SD, 150 or Duramax driveshaft it comes from the factory rusted... my ranger still has that new aluminum look, I dont polish it or anything... and my mechanics think Ive got some aftermarket driveshaft.

Id rock that exhaust if I was boosted or making some big numbers, just to hide the sound some.... I just like loud noises better in my opinion

 

yeh... happens all the time. lol

and yeah its not that loud i know.. i think its at a perfect volume right now.. cause at 75mph on the highway... my rpms are at 3k in 5th... and too loud of exhaust would get pretty droney

 

I have a 2.5" exhaust on my truck after the cat. has a resonator and its nots to bad on the highway.

 

My Driveshaft has 0 rust.

It feels aluminum, though. But I dont think it is. Galvanized, maybe?

 

its either aluminum or steel, take your pick

 

Probably aluminum then.

It wasn't very heavy.

 

I am running a full manifold back exhaust with magnaflow cat's and 2.5 inch piping form the manifold back with a flowmaster 40's series muffler. It has a mean sound to it and it sounds like no other ranger lol. And its a 3.0.....
