Do you think if I had Exhaust Depot do there y-pipe and add resonators, would it still be a beneficial gain, and would it help with rasp but still sound good?
adding the Y PIPE TO HFC with stock catback there will be LOTS O RASP AT WOT

Did you have this set up before? How was it? Because I have berks right now and I'm planning to get exhaust depot y-pipe. I want to keep the rest stock because I don't want it to be too loud.

Have you done it? I've heard this a few times but it doesn't seem like anyone has done it with the stock exhaust and I feel like maybe it was one persons opinion and is just getting passed around???

Really would like a solid answer soon as I have a good offer on a Y pipe.

I did Berk cats as well, I had them on my old coupe and I loved them. Definitely a noticeable gain in regards to torque and power. Chirps the 285s much harder now I would say do the HFC vs the Y-Pipe, but also cuz I'm a fan of the true dual exhaust system. Doing a dyno tonight of Berks HFC on the new 37 ( I wish I had a baseline to see what they jumped me to) Then doing the R2C so I can see what that gained me. I have a thread up about it for anyone considering it. Also if your interested to see what Berks do on a 37HR vs the 35HR (306 vs the 328 hp). Again it would be much better if I had done a baseline first

Rasp kicks in at 4k, louder than i thought it would be. Otherwise, it's definitely worth it
