Sleeving CCCs, aural suicide?

[robsco]

Merry Christmas all, to begin with.

Has anyone tried sleeving CCCs? When I bought the Tuscan a few months back, it was running a standard exhaust with cats. The cats were promptly removed... Not much more noise. Anyway, I have since ordered some CCCs which came from TVR Power, they're all fitted and I was expecting armageddon... But it never came. I can still barely tell any difference between the standard, catted exhaust setup and where we are now. The only option I can think of from here is sleeving, or are there different volumes of CCC cans, rather than just a blanket exhaust?

One other thing, as well as volume, the overrun is still very muffled rather than the artillery fire one would expect from a decatted Tuscan with CCCs. This must be rectified!

Thanks.

i have the loud ccc's and decay - it is loud, but you get an awesome snarl on the over-run/when lifting off.

The new cans you've just fitted, do they have perforated pipe down the middle, or is it solid? Also, do they weigh the same as the std cans or much lighter?

Generally when people mention CCC's, they are talking about the original loud configuration which is a solid pipe through the middle, with no wadding in between this and the outer skin. This is what amplifies the noise and gives a more raspy/angry S6 sound.

You can get the cans made up any way you want, sleeved (solid pipe), half sleeved, with wadding/without wadding etc. I'm currently running decats and 80% sleeved cans, with a small section of perforated pipe in the middle, and with some wadding between the pipe and the outer sleeve. It's quiet around town, but all hell breaks loose when you give it some beans.

Worth checking what configuration your cans are as effectively CCC's as they're commonly called are normally solid pipe all the way through anyway so are already "sleeved".

I had planned a litte video this year to show a few different configurations but never got round to it. Maybe that should be my new years resolution!

I would suggest a hearing test if cannot tell the difference between standard exhaust cans with cats and decatted with loud cans!

Kinda had that thought myself! I just had CCC's on mine with standard cats, everyone noticed the difference!

I'm running the original loud (solid pipes) CCC's with cats and I will never put the old cans back on, the sound is awesome in my opinion, especially on a tunnel run! Decatted is too loud for me but we're all different.

Robsco - As others have said check to see if they are perforated or a straight through pipe. I bought some silenced powertech cans (made by the guy who ised to own CCC) and was hoping to queiten down mine! It hasn't done so and they;ve been on the car for all of a month!! So if yours are quite silenced then I'd be interested in doing a swap with you if you wanted? Could record some sound clips of mine against my friends standard red rose if you wanted.

[robsco]

Thanks for the replies. MrChips, they are definitely perforated, I took a photo but I can't post from my telephone. Toady, what do the Powertech cans look like? I'm going to give TVR Power a call and see whether they offer ones with no wadding etc.

As above post mine are the carbon ones. They are also perforated but loud!! So I'd like to repack them with more wadding if able to, or swap with someone else's quieter cans!

[MrChips]

Rob I think if yours are perforated at the mo then easiest/cheapest to try is to sleeve them yourself. This will definitely increase the volume and give a raw sound.
If they're still too quiet then go for some that are sleeved but without any wadding.
If that's not enough then remove the back boxes.....
And if that's not enough then you better start learning sign language

Robsco, they look different to mine. I'll try and upload a pic of mine today.

It would be a shame to sleeve those. One of the advantages of ccc's over standard sleeved is the weight. Unless you have extra support, the weld supporting the cans has a tendency to fail with the extra weight caused by the s/s pipe.

However, it almost looks as if your perforated section can be removed. Wonder if it's possible to have it replaced with a non perforated pipe?

My Tuscan is decatted with Powertech non-perforated cans. It can be a little loud when making an early morning departure

That is way too loud and raspy for my liking but each to their own.

Now THIS is what I'm after.

I went from std Tuscan exhaust, then sleeved them - noticeable difference. With the perforated originals there was no overrun pops/bags at all. When sleeved, this was the biggest change I noticed, plus a deeper more burbly V8 kind of sound.

I only then went to the Powertech ebay cans because I preferred the look of the stainless finish to the original "carbon" ones. But I also noticed a difference in sound with these - without wanting to go all What-HiFi, they sounded clearer / more defined - and slightly louder still

The powertech ones were also noticeably lighter than sleeved std cans.

P.S. decat + sleeved/unsilenced sounds awesome in the youtube vids but for me probably would have been too much!
