So my stillen y pipe is going bad i think.. Under acceleration i keep getting this hissing sound.. i think it may be the flex going bad. any suggestions?

 

Is this a 1st gen y-pipe? As in 1st gen Stillen?

 

??? idk? does it say on it?

hmm...hard to tell.

 

Check your flex section. You might have a leak somewhere.

 

How old is that flex pipe? Shouldn't be leaking if it's only a few years old.

 

Quick fix idea... Drill a hole in the pipe to let the bee's out, after they leave seal it back with some ABC gum and VIOLA!


Seriously though, mine does the same thing and I am pretty sure it is coming from the flex pipe. I can't faintly hear it while under the car and a buddy revs it, not as loud as when there is a load on it though. (driving)


96 SE Manual with a little bit here and there...

 

Can faintly hear it... Sorry

 

That is a Stillen 1st gen. rare.

 

Yeah it sure does look like one...OP I am assuming you bought you car like this? If you get a new y pipe, I am sure many people would be interested in buying yours in the shape its in (and getting a new flex put in). I know I sure as hell would be.

 

never seen a ypipe come with progresso soup, that is rare lol.

OP do you have a resonator?

 

mmmm soup. I just woke up, feeling real hungry... and could sure as hell go for some soup!

 

Nice, I didnt know the 1st gen stillen y is equal length. I didnt even know anyone made an equal length y pipe for 4th gens ever.

 

 

yes whatever comes with a greedy sp2..

 

rare piece eh? um whats a the going rate for one of these pipes? $$

 

Not made anymore, so if you can get your hands on one, get it.

I paid 250$ for mine (used) 10 years ago.

 

its greddy not " greedy" psshhh, you spelled it right it ur name...

 

...that's one greedy pipe alright...eating progresso soup..

 

great... THANKS now i want soup lol

 

My "hissing" sound comes mainly from the gasket on the rear header, I would make sure that gasket is fine before I'd go onto replacing the flex pipe.

 

i think the gasket may have failed (between test pipe and ypipe) i used one of those metallic cardboard gaskets. Not a metal one like the OEM.
