Hi There, I have just purchased a set of headers for my P6 from ebay, item no. 232456041022. I already have an uprated stainless exhaust, cone filters, heads from a 1998 3.9, hurricane cam. I still have the SU's (early HF's I think (1972 3500S)The needles were uprated from the original BBG to BBW on...

Thanks Ron, I guess I was hoping against hope, it's a shame, as they are such a good price. I know that block huggers would fit, but they don't look as though they would give much of a boost, as they are not that far off the std. ones.

I have seen a set of Hedman headers for a Rover 3.5V8, & wondered if they would fit my P6 3500S?

Thanks Spongo, I was hoping someone would validate my choice. It looks like I will retain the original manifolds for now, as I can't justify spending hundreds of pounds on new ones that aren't much better than the originals. Thanks for the suggestions though everyone.

Thanks pocketrocket, I did contact powerspeed by phone & they never got back to me :0( I spoke to zero exhausts & the guy did sound good, but needed to look at the car first, which is difficult because of working hours. I have found someone in Dover, called powerflow, to do the job.

Sorry DaveEFI, I probably did miss your point, I thought you meant the sound differing between the tubular manifolds & the originals, as I always thought that the tubulars give a deeper sound, which I like. Mine sounds a bit "waffly" at the moment, like it may have a blow or two, especially at full ...

The idea of swapping the p38's over sounded like a good'un, in fact I couldn't weait to get my head under the bonnet to have a look. Unfortunately, my hopes were dashed. The aperture is too small, & I don't want to cut it about, so back to the drawing board. I don't mind noise, in fact I don't like ...

I can see what you mean about exiting at the rear now! I have had a look at block hugger headers on google images & in all honesty, they don't look that much different to the originals that are currently fitted (3500S) I don't see much point in spending a lot of money on headers that don't add much ...

Thanks Quagmire, funnily enough, the first quote I got was from them. It would definitely be too quiet anyway. At the moment I have the standard system, minus the rear silencer, which sounds pretty good with a good gurgle at idle & a satisfying roar on the road. Maybe I will have to go with the bloc...

Had a better quote now, luckily, no cats needed on this baby :D . I presume the original manifolds are quite restrictive? if so, it would make sense to get new ones first, so that the exhaust can be made to fit these. Do P38 manifolds fit a P6? as these seem to be readily available second hand. Some...

Hi There, I am looking to replace my tired original exhaust with a stainless performance version. I have had one quote so far, which was a bit steep at 750 plus vat. I would also like to have some freer flowing manifolds, if I can find some at a reasonable price! (The place that quoted me for the ex...
