Peninsula Sports exhausts

[Dave Marett]

Morning,

Peninsula do Stainless exhausts, has anyone any experience of these,
especially on a 4.3 precat Griffith. My original system's a
bit "holey" but I was wondering if it might be a bit too loud on a
precat (not that I think you can have "too loud" :-) )

Cheers for any opinions

Ihave a sports exhaust on my 99 griff 500. I have removed my pre cats and the noise is quite fantastic. I would forget the BHP claims, we never had the claims to start with. I can only imagine your noise would be even more fantastic. Oh, i have a ACT exhaust.

Also have no pre cats and a sports exhaust from (Wedge Automotive-excellent quality and sound)on my Chim 500.
Would also reccomend a Mark Adams re-chip to let it all come together nicely .

If only the pre-cats are removed, how do you stand at MOT time? If it passes, fine (so why did TVR put them in?). If it fails, why not have them all out, as you have nothing to lose?

As the exhausts are made by Peninsula why not ask for a 'not too loud' system I am sure they can adapt to suit

[whitechimp500]

As far as im aware , the pre-cats are there to aid exhaust emmisions compliance when the engine is cold.
The main cat will still be effective enough to give an MOT emmisions pass as long as the engine and cat are hot i.e at MOT time make sure its tested whilst nice and hot.
Remove the main cat as well and youd better know a "flexible" MOT test station!! Naughty Naughty.

Not a bad idea, Peninsula have been really helpful in the past so I'll give them a ring. I'm not too fussed about the noise on the Road, I was just wondering if a sports exhaust on a 4.3 is "too much"

cheers

How did you go about removing the pre-cats ? What does it involve ? Were there any power gains ? I have a Peninsula sports conversion on my 96 Chimaera and just wanted to finish it off.
P.S. I'm an M.O.T. tester and you can't test the emmisions on a catalyst equiped car until it at least hits 80 degrees.

It aint easy, hammer and chisel. I finally used a 30cm long masonary drill on my hand drill to make as many holes as poss. Then it will sort of collapse on its self. Kind of buggered it though by going at it a bit too drill happy and went through the metal. My local TVR peeps welded it foc during the service, well they had to do something for the £500 to change the oil.
It is worth the elbow grease, i hate to mention other manufactures, but Ferrari scream springs to mind.
