sorry to hijack the thread - but did you find a suitable 3.2 in the end Al? any details if you did (sorry if you've already posted it elsewhere!)

Sod that ... how much for an exhaust for my new 3.2 [] ...
not bothered about the cats (don't even know if they even have 'em!).
I've come from a de-catted and Tubi'd V8 Ferrari so volume is not a problem, twin outlet, one at each side would be nice mind you [

No point in replacing the pre-silencer - its a straight thru design and actually helps torque. Using a pipe off the pre-silencer is freakin loud. The tried and proven method with 3.2s is to buy a sport rear box, dyno it and send AFRs off for a custom chip OR replace the whole lot with SSIs and 2-in muffler + dyno + remap OR replace the whole thing with an H&S equal length system + dyno + remap. I list them in this order as indicative of escalating price, though the second and third options are relatively close in price. I could speculate on hp and torque outputs but perhaps 911SSC can enlighten us on his H&S results before I speculate - assuming they have dyno tested the 20hp claim in their adverts[

Nope - SSIs are a reproduction of the early 3-into-1 extractors with heat exchanger over the top. Its an equal length system with a nice collector. Quality is very good and should last a lifetime. The LHS and RHS are separate and hence a 2-inlet muffler is required. In concept it is like the H&S system above, the major difference being the primaries 1 5/8 inches rather than 1 3/4 inches on the H&S. The H&S size is optimal for peak hp on a 3.2 but will suffer a fraction in midrange torque - IMHO. The HEs are also much bigger on the SSIs and shold make more heat more quickly. SSI are just the manufacturer but they have become synonomous with this type of header system.
They look like this fresh from the box:

Thanks richard, that looks a lovely piece of engineering, but if they are up in the region of H&S, and, presuming my current heat exchangers are ok, it is just too much to spend just now I think.
How much are we talking about for a sports rear box and are there any in particular that work or sound better than others? And can you get twin outlet boxes to fit the rest of the standard system?

I took this route for a while by replacing the rear box with the Fabspeed pipe. As RB said unbelievably loud - sounded like a racing car. Way too much for everyday use.
I had almost new good quality stainless heat exchangers already so just went for an H&S sports box, pre silencer and crossover pipe.
Now sounds great when you want it and breathes much better. With a healthy engine this option with a Steve Wong custom chip should make 250bhp+ and not cripple the finances

M&K from Pelican is another option that works out well on current USD x-rates:

Mine's a 2-in 2-out that I polished myself. Very lightweight mufflers, with great welds and nice sound.

I like that Pelican polished 2 in 2 out! Is that the same as you have Richard?
If i order one of those, obviously I need some thing to adapt my current system to fit to the twin inlets, but what and where from. That exhaust system with the exchangers looks a right puzzle and no two cars seem the same!
Is that the normal arrangement down the left side of your Twinny that fits onto your single inlet?
And would the 1 in 1 out sound any worse than a 2 in 2 out?

You pays your money as they say.
M & K make a single in single out (top of the page) I have the H & S version - saves cutting away the O/S rear valance to accomodate the other tail pipe.
Sound wise - not sure, never compared mine against another. However if you take out the pre-silencer and fit the sports pipe you get a nice crackle and pop on the overrun.Very childish , but sounds great!
Some talk of reducing torque, but mine was compensated for when I had my chip done, so now makes around 220lbs/ft anyway.

I have the M&K 1 in 2 out system that Ben can make on request. This is a very good and high quality piece of kit. It also works out cost effective with the current exchange rate. Check out this link to cut the valance and this one to see a small write up.
You are more than welcome to meet up and have a listen and see if it's what you are looking for

Hang on ....
Twinny, on Jacobs thread you said ... "Just under £800 for the H&S sports system fitted, including the cross over pipe."
I was informed by Ian that one of his H&S systems would cost me about £1500, which immediately put me off.
Jacob - I listened to your sound bite a while back and it does sound nice and, as you say, nowhere near too loud. Was it purely the back box that you bought and how much was it all-inclusive please?
