I was under my SS today, so I decided to take some pictures of the Y-pipe the previous owner put on. The car is dropped pretty low, so that may have been the reason for the change. The car has kind of a high pitch sound to it when I gun it. Almost the whole Y is flat. Check out the pics and give me some opinions. The car is totally stock except for lid and flowmaster catback. I put a quart of oil in front of it to gauge size. Thanks.

 

Looks like a stock y pipe too me, all of them come flat on the drivers side...

 

that looks like the factory Y pipe to me. Long tubes and an ORY will get rid of that for ya!

 

factory y pipe

 

Throw some LT's on there, you won't have to worry about choking any flow after that!

 

I just don't remember the Y on my 99 being that thin. There are two aftermarket cats welded into it too. Maybe that's why it looks different.

 

hmmmmm.... wonder if he welded some cats into the stock Y? but then.... what happened to the factory cats...?

 

+1 let get some pics upstream where the factory cats go- right off the end of the manifolds.

 

My guess is he took the cats off to Gut them, and rewelded them in.

That also might be the "High pitched" sound you hear i think

 

These do not look like factory cats and I'm not throwing any O2 codes. I'll see if I can get some more pics. Thanks.

 

thats the stock y, dunno about that cat situation

 

YUP....

 

looks like a stocker to me, and it sucks mad dick, idk what kind of gains you'd get replacing it but a set of lt's would probably help a hella lot

 

Damn stock Y pipes are ugly. Definally do some longtubes. Night and Day power wise man

 

you won't regret getting LTs and a Y pipe if you do.
