RE: ACT launches exhausts for Griffs

ACT stainless steel exhaustTVR induction and exhaust specialist ACT has announced that it has a new sports exhaust available for the TVR Griffith and Chimaera.
ACT launches exhausts for Griffs
Hear the stainless steel system at the Growl
ACT stainless steel exhaust
Manufactured by JP Exhausts exclusively for ACT, it features twin cherry bomb silencers. It's a fully stainless steel system from the Y piece. It requires no other modifications and uses existing mounts.
- Standard tail version: £460
- Quad tail version: £575
Both prices are exclusive of VAT, and for supply only -- ACT says it can arrange fitting if required.
ACT will have at least one Griffith fitted with the system at the Growl this weekend if you want to hear it before you buy.

Discussion
They look like a really nice bit of kit.
But have ACT or any of the other manufacturer though of making manifold that do not join into one pipe then back out into two for the bit in the picture, 2 headers make nore sense to have two pipes running back from these? (Linked further back).

Wow, that sounds great. As for having two totally independent exhaust pipes, well, AFAIK with a conventional V8 that has crank throws 90 degrees apart, it both performs better and sounds better if the exhaust is joined, provided it's done right, hence crossover pipes.
With a flat-plane crank V8, such as the Cerbera, Lotus, and Ferrari V8's, since they're essentially two independent four cylinder engines with a common crank, they work better if the exhaust pipes from the two banks of cylinders stay completely separate.

Not quite true .. we gain 5-8 brake linking the cerbera exhausts.
Joolz, Miguel,
I mean the twin full systems being better than compromised one link system, yep two linked system must be best for all V8's. What I was told my the chaps that built the TSO and Holden systems and they are not flatplane engines - yes firing order isn not same as an RV8 but not running as 4 fours.

Quad Pipe - that is a bit cheesey isn't it. Ywo nice big ones best.
Nope! FOUR nice big ones best! (Depending on what you're taliking about!)
-a pic would be good, tho'. Sure my old stainless one's started to rust badly all of a sudden
Started saving the pennies already - what's the effect on BHP, more or less?

I'll be interested to hear how it sounds against mine, as I need a new soorst but might just get some custom bits made to patch up mine
I thought that you had a sports system??
I don't think it will make the car pop and bang any more,just if it does it will be louder.
Road Legal??? Well I've not had any problems so far.

So what would be the advantage over a "standard" exhaust conversion which typically is a third of the price?
Your not the first person to ask that,i've seen it posted elsewhere already.I just can't understand why people want to modify the backbox to improve sound,when if they spent their money at the other end,i.e. the manifolds and 'y' piece,then they could get the better sound and also improved performance Edited by reichejh on Thursday 3rd August 20:02
.Also,if you remove the cats,you can get rid of some of that unwanted under bonnet heat.To me it's a no brainer

.Also,if you remove the cats,you can get rid of some of that unwanted under bonnet heat.To me it's a no brainerPart of owning a is having a nice sound on the car, I cannot understand how one modification can provoke so much division. Surely if someone wants to change the wheels on the car then they should consider the performance impacts of fitting say 17's or 18's such as increased strain on the bearings, suspansion componenets etc. Loss of acceleration and top speed, higher prices of tyres. But it doesn't seem to create the same sort of discussion that this has.
Possibly adding modified Y piece or sports manifolds would push up the insurance too much? Maybe their exhaust needs replacing. All it is is adding another option for people.
As for spending money on the other stuff. Moded Y piece, Sports manifolds, stage 3 heads, triple throttle bodies CF Plenum, smooth induction kit, chip. Been there, done that
What's left?Although the sound of the new system is great, it's maybe a liiittle toooo much like the boys in scooby doos and phatted up hothatches - I'm not convinced it's an improvement over the original Griff sound which is mellow as well as a bit raucous if that makes sense! and there's always the danger of just trying too hard.....and just pi$$ing everyone off rather than impressing...but I'm looking forward to hearing it live at the Growl before I decide.
