Speed6 exhaust

[DJR 7]

Sure this has been discussed before but I'd appreciate your input.
I've recently purchased a Cerb 6 and I'd like to replace the exhaust for something a little more throaty, I find the car performs well so not really looking for improved performance but really like the burble of the v8's
Thanks

I'm sure someone on here has recently had a bespoke Sp6 exhaust manufactured by ACT (i think).

A de-catt makes it sound better and lots of pops and bangs on the overun. As posted above I think ACT do a Sporty back box for the SP6.

Mine has a standard exhaust with a decat and wouldn't change it. Pops and bangs on the overrun as good as any ajp. Sounds great just need a TVR friendly mot station.

Hmmm - you want an exhaust because you want the 'burble' of a V8? Firstly a Cerbera V8 will never ever burble, and secondly, you have a straight 6 engine.
I'd go to a decent custom exhaust place and tell them what sort of 'sound' you want.

[DJR 7]

Thanks guys I'll give them a call.
Now how do I tell them what noise I want from my straight six ...... Got it BURBLE!!

Imho you bought the wrong car. I agree the cerb is great and I owned a v8 one myself.. however the classic v8 burble is caused by 90 degree config v8 pendulum effect. Griffs and chimps will deliver that In buckets as it is at heart an American Buick but even the v8 in the cerb won't do that. The layout in a cerb is 75 degrees and the noise is totally different. A six is diffrent again and will never be described as a burble.

Decat it, and sleeve it and you can get something more of an Italian howl but American it ain't.

Think that may well be me! I had mine decatted first with ACT decats & kept the standard exhaust.It definitely made a difference.A lot more pops & bangs & much cooler inside.

I too was after a sound "more like" the v8 if poss & I too got told to go buy one then.Too late for that.I was very pleased with this set up,& might be a good idea to start with just the decats to see how you like it.

I wanted more so went back to Tim at ACT to enquire about their big bore system they do for the ajp & other speed 6s.At the time they didn't do it for the speed6 Cerb.....they do now.Mine was the first & Tim said he was going to give it a part no & market it.I don't know if its up on the web site yet though.

It's tight for space under there but Jp have done a cracking job.It makes a MASSIVE difference! Sounds a different machine now.Basic note is a lot deeper & louder.Pops & bangs have gone mental & have me laughing like a loon.Wind it up & it sounds like an angry demon.It's a lot louder, a lot deeper, more purposeful & menacing.I absolutely love it.

You'll never get that v8 burble,but this has got to be as close as it'll get.It really makes a difference & does sound sooo good now.Thank you ACT.

It is loud though. :-)

Hi Dave were you able to host a video of the new exhaust anywhere?

[DAVEY DEE]

I will try.Did it on my phone but it sounds awful- really tinny & distorted.It may play back ok on pc but haven't tried it yet,coz being a muppet I Transfered it off my phone & then couldn't find it! I'll make it my priority.Only other thing I have is a Sony camcorder.Tried it on a flip & it sounded pants on that as well.Maybe I stand too close.

you`ll never get a v8 sound from a straight 6 full stop.


you can change the tone to eliminate the raspiness, and achieve a bassier note, but never a burbling v8 noise I`m afraid, unless you change cars

Not necessarily he could go for the "Reverse Clive" option

I understand the concept of the v8 and have indeed owned a chimp that was a fantastic car, I bought the Cerb 6 as I'd always fancied one.
The sound I'd like to achieve is a deeper one than the current standard exhaust, I think I'll try the de cat option as has been suggested, who knows one day I may find a good 4.5 ...... Problem solved

I'm sure I'm going to regret this ...... What's a "reverse Clive" ?

Dave

This sounds exactly what I'm looking for, owning one you seem to understand, I'll give ACT a ring tomorrow but in the mean time I'll check the web site to see what they have.
If your at the NEC on Sat let me know and if poss I can hear a recording? Cheers D

Cheers Dave, did look on the ACT site but they only advertise the de cat option. D

Don't worry it was just me trying (and failing) to be mildly amusing - Clive put an AJP in his Griff, looked like this:-

[DJR 7]

That's impressive! Now I know what a Clive is I see the logic in the " reverse Clive" is the car seen at many of the meets? I'd like to have a nose.
