Looking for a Y pipe for my '07. What is everyone using these days. Cattman and Raceline aren't making these anymore? I see them on Ebay and they don't look like they have O2 sensors bungs. Isn't there a spot for them on the stock pipe. I don't have the car here to check. I used the search function and it gave me 20 pages of nothing that answered my question. Any guidance is appreciated.

The stock Y does not have O2 bungs. The sensors are in the manifolds and catalytic converters before the Y.

What is your goal? Damaged or rusty parts? More horsepower? Extra noise?

 

Just looking to replace the factory pipe that is leaking at the flex section. Extra HP would be an added bonus

 

When the flex sections on my parents cars (07 Max, 08 Quest) started leaking I had them get it repaired at a local exhaust shop. It seemed the most sensible for someone staying legal and not looking for power gains. It was between $500-700 per car, using stainless. Winter turned all the fasteners and flanges to crumbs, I didn't want to open that can of worms.


I had a Racingline on my old Altima 3.5. I don't remember it being anything special on the old butt dyno. Fitment was off and the flex rusted out after 5 or so years anyway.

 

Yeah I might just take it to a shop and have them weld in a new flex piece. Thanks for the info
