Is OEM Exhaust 3 Or 4 Pieces?

hl0m4n · 12-20-2009, 09:11 PM

looking at the entire oem exhaust does it fall off in 3 or 4 pieces? from the pic im assuming 4 the cats, xpipe, connecting, and muffler?

or is it just 3 pieces cats and xpipe welded together, connecting, and muffler hence slip on exhaust systems only being connecting and muffler...

3 pieces:

X-pipe

Left muffler

Right muffler

The connecting pipes are part of the each muffler assembly. That's why you have to cut them for certain aftermarket exhausts.

wtf lol

It's 3 pieces Muffler and connecting pipes are all together, midpipes come of in two sections from the primary cats and secondary cats with resonators rear section

sard · 12-20-2009, 09:48 PM

It's just the X-pipe and the muffler ..

Green///Hell · 12-20-2009, 09:58 PM

Oh snap your right, for some reason I forgot mines clamped together because its been chopped up

sard · 12-20-2009, 09:59 PM

Oh haha

hl0m4n · 12-20-2009, 10:31 PM

wait what

.

ok the connecting pipe and muffler are connected hence the slip on exhaust systems being 100% bolt on.

now is the cat and xpipe connected or does the xpipe fall off the cat? by cat i mean the front pipe with the 02 sensor.

Wow, that was pretty bad of me. I was thinking of my RPI setup, it's been so long since I was stock.

Stock is two pieces. X-pipe, and muffler. The connecting pipes are integrated into the muffler.

hl0m4n · 12-21-2009, 12:41 AM

ok... entire section 1 is together and comes off without cutting. now are you guys sure that part 3 and 2 are not connected as well and that part 2 can be replaced (xpipe)?

mixja · 12-21-2009, 01:55 AM

The stock exhaust system is four pieces:

- 2 x Headers (#4 in the picture above)
- 1 x Down Pipe/X-Pipe (#2 and #3 in the picture above - i.e #2 and #3 is a single piece)
- 1 x Mufflers (#1 in the picture above)

MrHarris · 12-21-2009, 05:54 AM

^picture up there labeled 1-4 is correct except most people don't consider the headers the 4th section.

2 and 3 are one piece as mixja said.

m3pyun · 12-21-2009, 09:48 AM

everything from headers back is 2 pieces. The cats/xpipe is 1 piece and the muffler/connecting pipes is 1 piece.

no it's not. Headers, xpipe, mufflers. 3 sections if you count headers.
