The best I can tell from the pix and putting a boroscope in mine, is that there is a 70* bend that connects the inlet to the u bend. When the chamber is opened up you " should" be able to see and remove it. I may try it on mine when this polar vortex frees up here in Chicago. I just don't want it to sound too hollow or chambered like a flowmaster if I remove all of the insulation.

Not sure if anyone has done that before but to me seems a sensible idea but as said I really have no idea about these things.
I reckon you ought to man up and brave the cold and give this mod a go this w/e!!! Then report back to me your findings

Lol, well we'll see. I'm betting it won't happen this weekend though. 6-10" snow Saturday with the Super Bowl Sunday. The cars in the garage but ill be busy dealing with the snow.

Not sure why you would want to block the u-bend off - we just cut the u-section off completely and removed the sound deadening material. I would love to send you a video clip of my exhaust, but I am a moron and my 12 year old is not here to help me out.

"James,

Without hearing one in person I would think it would sound to hollow or echoey for my taste. I'm not a fan of the chambered flowmaster sound and once you remove the material, there's no going back. I'm guessing removing the u bend "should" make it 50% louder with out changing the sound too much. This obviously is all trial and error though.
I would love to here yours if you could get some sound clips uploaded.

We can always get together again and I will bring my gopro to make a video of that beast of yours rumbling through the jungle!

There is another thread going on this forum where the owner has ditched the muffler completely and just gone with a Y-section from the main pipe going into the two exhaust tips. This is very similar to what mine sounds like, but lets see if I can get a clip posted tomorrow.

Anyway James, I can tell yours is going to sound like a beast with the system you have. 88mm pipes, no cats, long tube headers and gutted mufflers
Trouble is my car needs to sound reasonably subtle as I live close to my neighbours and visit clients in my car. It seems like stockC43 is on similar thought lines to me but then I'm making it up as I go along

Im thinking just cut the orange bit and leave the rest. So cut it at the chamber instead of the u bend. Then if you dont like it go back in there and blank off the u bend aswell.

I would have thought the principle of opening the small chamber would have been looked at before though. I've only seen threads on opening the main chamber.

I left the U-bend and length of the exit tubes intact because I decuced they were there to remove a specific frequency that this motor caused. If I just wanted loud I'd strap on any straight through design and call it a day. As a daily driver, I wouldn't trade my gutted mufflers for anything at this point. Very aggressive at wot, mildly aggressive from outside the car at idle, but from inside they barely sound more than stock except when you don't want them to.

I had my stock mufflers baffles cutout and all material removed
My advice is DO NOT CUT ANY METAL inside the muffler. I think removing the fiberglass stuff is ok
My mufflers ended up droning so bad they RATTLED THE MUFFLERS and it sounded like some beat up old truck.
The problem was I had hacked up the mufflers so and I couldn't easily return them to stock
So I had to pay $500 for some used oem ones.
I now have some 3" cutouts installed right before the stock mufflers and it sounds awesome!! Quiet when I want, screaming loud at the press of a button
IMO exhaust options include
1. Straight pipe. You can reinstall the muffler later if needed
2. Open muffler and only remove sound dreading. Again could reinstall if needed
3. Cut outs
The reason I stress not cutting the stock mufflers metal inside is the high price of a stock replacement or difficulty going back to stock. Think twice before hacking up your stock muffler I wish I would have!

Great info Cheers
I hope to take my car into an exhaust shop this week and get them to have a quick look and decide which way to go. At this point I'm thinking of getting them to cut open the small chamber and cutting the main inlet so it discharges into the small chamber and therefore not going into the main chamber via the u-bend. Not sure what this will do but it will be interesting to see inside this chamber and try it out.
Would be great if someone had already tried this but.......

Omg I just realized that there is a video of the tectite grey e55 with the gutted mufflers on this thread THAT IS NOW MY CAR! Yup do not do what those photos show. The muffler rattles like a beehive at certain rpms
Here's a photo of a muffler shop reinstalling some oem mufflers and the cutouts
Notice the color of the car??

Thanks for the words of caution
Duh, just reread your earlier post. So all of the visable perforated exposed pipes in the above picture were removed correct?

Yes, It was actually the previous owner who did everything, he's also a member on this forum, where I got he car There is a whole post he made talking about what he did He doesn't mention that the results rattled like a beehive He did a good job and it sounded awesome at full blast but the rattling muffler was a surprise even to him, (not his fault) I had to get those mufflers swapped out ASAP when I got he car I still think the cutouts are the way to go if your looking for crazy loud for cheap. I think the cutouts sound even better than the gutted muffler

I think another idea is to maybe keep all the stock internal bends and pipes but maybe replace the perforated pipes with solid straight pipes inside the muffler. I think the problem was the exhaust was dumping out inside the muffler and at certain rpms it rattled. Sounded really bad when it rattled.

I believe this is what was done. The previous threads show exactly what was done
