No, i'm afraid not as the exhaust was on when I bought the car. All I know is that it sounds amazing! I'll have a look through the folder of receipts when I get chance and see if they give a clue.

i had it made its a one off 2.75 SS all the way to the manifold,to realy hear it you need a tunnel run sounds much better than the vid Nick did.glad you're enjoying the car Nick

Leighton over at Sabre Tuning in Bristol makes a bespoke exhaust for the coupe or you could try Welsh Coast Customs down by the Transporter Bridge in Newport.

The owner is a genius with a bit of pipe!

Has anybody got problem with their aftermarket headers?

Lots of cheaply made Headers/Manifolds available here in the UK through eBay. Lots of users have had issues with them falling apart within a couple of thousand miles. Which is why you'll see lots of units going un-sold on eBay because of this very problem. People don't trust the quality.

That and the standard Manifold is good for big power - unless yours has cracked (even then you can weld them up) people just stick with OEM.
