If the SS/SC is 2.5'' tubing, what is the 2.4L's OEM catback diameter?
I'm asking this since I am considering putting the 2.0L catback on my 2.4L for much less $$$


(GMPP is also 2.5''... with a 2.25'' exit)

 

2.25 i think.

GMPP will be better then ss/sc exhaust.

 

So i get to pick a used 2.5'' SS/SC for ~$100
or a new 2.5'' GMPP exhaust for ~$600
hum...

 

The SS/SC and the 2.4L have the same exhaust! They're both 2 1/2".

 

Can someone back this up for me plz?

I was told that it was 2.25''. Are you sure it'S 2.5'' ?
If it is then great

 

lsj and le5 have the same exhaust.

the big difference with GMPP exhaust is that its a differnt resenator and muffler and mandreal bent pipe not crimped, thus improving your flow.

 

okay thank you, that's what I needed to hear

 

the SS/SC and SS/NA i thought have a 2 1/4 not a 2 1/2. and is the GMPP still a 2 1/4 ?

 

gmpp has 2.25" piping and is dyno proven to gain 12whp on a LSJ. The LE5 Has the same stock exhaust as the LSJ which is 2.5". The 2.2L has 2.25 Or smaller Exhaust... Search for the love of god.

 

i dont think the cars have a full 2.5, some of the exuast is 2.5 butone portion drops down in size to 2 1/4

so your trying to tell me the GMPP is smaller then stock?

 

get under you car and measure

/thread


the 2.4 (my 08) have 2.5in until the over axle section which it goes down to 2.25in.

 

Yes the GMPP is 2.25. And yes the 2.5" exhaust go down to 2.25 over the axel and after the DP.

 

Does the GMPP have the same step down and step up, or is just a solid 2 1/4 the whole way thru with gains coming from the Flow being greater.

im to lazy to get under my car and look. all i know is that my GMPP Trouing added(really freed) power in the upper RPM band

 

Take a look into the muffler of the touring -- the inside diameter is reduced in size -- that's why it isn't as loud as the Performance.....

 

ss/sc and ss/na are the same exhaust

 

and almost no gain on a LE5 (about 2 whp).

The GMPP exhaust is 2.5'' tubing with a 2.25'' outlet... it's not 2.25'' all the way

 

ok ok ok im gonna clear this up.

le5/lsj have the same exhaust

that exhaust is 2.5 after the resenator and necks down to a 2.25 before entering the muffler (right behind the axle)

2.2 i dont know because i dont give a ****.

hope that helps.

 

well thats good

all cat backs will give about the same, the cat back is justa small cog in the big picture, as in Intake,Headers,DP, ect... its all about the sum of the parts, not the sum of one portion

 

that is why i dont like neither they barely do anything with the LE5

 

thats just N/A 4 cylinders for ya, no exhaust will really do anything for a LE5 unless its a full exhaust.

 

yea i kno but when you do get the full exhaust u best know its gonna do somthing lol

 

for what it costs yeah.

im in mine for only 520 bucks

320 for the header/downpipe new and custom catback for 200

the cat-back really does nothing, i just modded mine to make it quieter do to lack of cat.

 

yeaa true what about the megan racing exhaust does anyone like that??

 

little raspy for my taste but affordable.

 

yea i kno it is raspy
