Hey new to the G community got a g37s I currently have Invidia test pipes and I’m thinking of putting on a Megan racing y pipe did anyone do this setup and is it going to sound good?

 

Y pipe won't change the sound. All of them will sound the same. What will change the sound is what is behind the Y pipe.

 

Don't recommend it. Just about all after market Y-Pipes have a collector that is 3''. I had one such Y pipe and with the TopSpeed Y-back, it sounded pretty good. Installed test pipes and the car sounded like a bag of ***. Nothing like the videos I had heard. Switched back to the OEM Y and the sound cleared right up.

 

yup the small Y pipe diameter is holding back the rasp. But also power lol.

 

It's the least restrictive part of the OEM system. No more than 5 hp to be had from upgrading based on what I've read. Main reason I installed the part was to enhance the sound before the test pipe install. I'll happily exchange the small HP bump for a better sound.
