The only one I see there that is a direct stock replacement is the SLP31035...

Do you have that in stock...?

Just to be clear, the SLP F-body Y-pipe does not include cats. I was referring to the SW ones with cats.

I understand... I need just the y-pipe (made from stainless) to fit behind stock cats (which are already on the car).

I have an SLP stainless Y. It's their 409 stainless I guess
because it got pretty brown in the year or two it was on
the car. It's not the greatest fit (had to beat it and the
X-brace) and it gains you nada.

My factory y-pipe is doesn't hold inside the i-pipe even tho the clamp is tight... it rattles and allows the i-pipe to slide back/forth (very annoying)... I used a pipe expander several times to open it up and make it fit snug, but now it's not holding anymore, seems to be splitting and falling apart in general, it's a rusty mess.

Hmmm, so 409 stainless still gets the brown color... but it doesn't rust, right? (just turns dark).

I need this pipe every two years (you know why), rest of the time I run Dynatech LT's.

I remember when you still had those sitting around waiting to go in. That was around the time I installed them on my 98 5 years ago already damn.
I would still have them if I didnt have to sell the car but those dynatechs are imo the most underrated for our cars. Should be mentioned with kooks,qtp,arh

Good luck with emissions Joe

They are definitely underrated... they have excellent fit/quality, produce definite increase, make engine sound modded/bigger... trigger car alarms in parking lot at work
