2.5" TD's H-pipe into GMMG
I should be finishing up my over the axle true duals this week. I went with the 2.5” stainless flowmaster mandrel bent universal kit, Founders PHB relocation, magnaflow metallic substrate 3” cats, H-pipe, 3” to 2.5” reducers, and am tying into my GMMG catback.
I will post pics and a sound clip but I remember seeing someone else that did something similar. The problem is I can’t find the thread. Anyone have it and/or a sound clip?

Just finished this up. I must say, it sounds absolutely nasty! The car just sounds mean. All rasp is gone but still has that GMMG sound. It's a tad loud for my taste but still ok. It's on my procharged 402 car so I'm sure on a 347 it wouldn't be as loud.
I'll try to take a sound clip soon and post it.

All that said, I just got a great deal on a catted kooks TD system. Taht will go on my blue TA though. It would be great if Kooks would offer a 2.5". It would be quieter, not melt gas tanks, and not hit against everything underneath the car.
Anyway, I'll post pics and a sound clip asap.

If the muffler inlets are truly 2.25" that will likely pose a restriction as well. My car had 2.25" duals from the old engine setup and piece by piece it transitioned to 3" and each time part of it opened up the car went a little faster. Some guys do contest that since the exhaust gasses near the rear of the car are cooler the smaller pipe back there is less detrimental though.
But if you aren't after every little bit it's not worth worrying about. Setups also vary so in some cases I can agree with you there might be no gains

Not looking for a 2.5 vs 3" argument. Just didn't think it made sense here or at all for my car.
Thanks for the compliments. I was putting some finishing touches on it last night. I will have a sound clip over the weekend. I actually wish it sounded a little smoother than it does. I might have to add some resonators.
Awesome. I actually wanted the bassani kit but couldn't see hacking up a brand new system to fit my headers. This was cheaper and I always wanted to hear what it would sound like. The bassani system sounds excellent. I wish they offered it catted for headers.

Sorry for the long delay on the sound clips. the car is down right now for some other work. I just don't have time to get it back together and get a good sound clip. Once I get time to get it back together and running, the first thing I'll do is get a sound clip.
