Ghl Exhaust
I recently installed the GHL exhaust for my 2005 c6 (M6), however my butt dyno is saying that the car feels slower. Does any one have a dyno on the GHL exhaust? It does not show on their site. Thanks in advance.

Stock, except for GHL cat back my C6 baselined at 348RWHP, about average for a stock LS2. After dyno tune, 365HP. A GHL catback may not add any HP, but these numbers indicate to me that it certainly won't lose you any.

I'm thinking about the GHL for just the reason you stated, good sound and very little cab noise differ from stock. But was not pleased about the design, it looks like one muffler with small pipes running into big tips? It may not be good for the HP?

Mine has a great sound at idle and at WOT it gets pretty mean. I do have a cam and L/T headers on my car (C5) and I get plenty of compliments

That sounds like the design for the A6.

[QUOTE=Smokin1;1561949208]Sure looks like two separate muffler cans to me. They might be welded together for compact installation but they still look separate.

GHL has two different systems for the C6, one for the A6,a contained unit that looks like one chamber (muffler) ..MN6 has 2 seperate mufflers ..I have used both the A6 and MN6 on my Vettes..Muscle car sound,increased power and a great looking system..Give Brian at GHL a call..they stand behind their product
