I was wondering if anyone bought any Y pipes from UPSW before. I'm looking at their Y pipes for an 08 M35x and the price is great/low for a direct fit, but the pic isn't great and I can't see if they did their bends/curves properly or improperly crimped it. Hoping someone has experience with their Y pipes.

Or if anyone knows a resonator exhaust section that has a 3 inch inlet and 2.5 outlet for less than $250 let me know, that way I would instead pick up a Megan Y pipe instead that I can get a deal on since I can clearly see how that is built.

I've never heard of them, but just visiting their website IDK if I would trust them much. What they call a "Y pipe" on their website for the car is actually what everyone else refers to as mid pipes.

If you are trying to adapt from one size to the other you can easily do that at any exhaust shop. Or use these and make it even easier/cleaner for them to adapt:

That's not their Y pipe, that's their resonator exhaust section, I don't know why they put Y on that. This is their Y:

They have an M35x version that is not listed. But from what I'm told the 2009 G37x fits the 2008 M35x as well.

I was hoping to stay away from the need to cut off the flanges in order to couple the sections, I was going to put it on myself.
