964 sports exhaust

Hello 
 
I mate is looking for a sports exhaust for his 964 tip. Can anyone recommend a good brand and one they may have put on that sounds great and is well priced. 
 
Thanks Phil

A cup pipe instead of the middle silencer is a low cost / great effect solution.

A cup pipe is all he'll need. They sound fantastic. Depending on year of car, if an '89 you can also remove the cat as only legally reqd from '90 onwards. Makes a slighlty deeper note without. A cup pipe also removes some weight from a good place to lose it. Another option is to replace the the final silncer with a swan neck pipe, but I prefer the cup pipe option. Do not replace both though!

Alternative to the cup pipe option previously mentioned is the final silence delete with G pipe to replace it.

I really fancy the ' Singer' style centre twin outlet, somewhat similar to the modern GT generation Porsche's but I have never seen them advertised, they seem to be manufactured by the specialists such as Singer, Paul Stephens and Rennsport. Has anyone seen a manufacturer of this style of exhaust?

You also might want to google 'porscheshop reviews' and look at reviews on trustpilot if you are thinking to buy from them.

All these seem to make some nice noises, but do any liberate any additional horses?

Looks like about 4 HP from steve wong's site though I've not heard people doing this for the HP gains.

I did look at stuff like a G-Pipe etc when I first got mine, but, although noise is nice, without additional power, I'll pass.

I haven't any experience of changing the exhaust system but have kept some notes for if I do.
I ran a 964 without cat and primary box and it started to get too loud for trackdays because the pressure on the rear box was too great and loosened some baffles. When I put the primary box back and fitted G pipe not had any issues. I was told the back box wasn't designed the pressures that the primary one does.
I believe you can delete the cat if your car was registered before Sept '92.
To get more hp a better designed exhaust system could liberate up to 10-20hp so I've heard as there is little difference between our engines and the 993 except for the exhaust system. The 993 system has 2 manifolds that remain separate down to the primary box instead of the 964 that combines the output of both manifolds into one before going through the cat and then the primary box.
There's Hayward & Scott who I've heard good reports about.
https://www.haywardandscott.com/porsche/911/964/porsche-964-complete-system-single-outlet.html
They make a twin outlet version too and have a 993 style system, I don't know whether the rear tray is redundant but expect it is.
TT Exhausts I know nothing about, based in the West Midlands who make a single outlet and 2 versions of the twin exhaust, one like the turbo and the other like the GT3.

You have to be careful to investigate if you will still have heating inside the cabin or not when you change the exhaust, that was another issue that put me off.  Also, getting it to fit may not be as straightforward as a standard system.
 
If you have the money, what you really need this piece of German engineering which will fit and make a difference.

This issue discussed in a thread I made about 4 years ago, although I opted for a repair to mine, which is holding up well.

You'll also need a couple of hundred quid for the bumper valance, plus paint, of course.
 
The fitting could run to a few quid too

Peter both the companies I mentioned have fitting service which is what I would go for personally.
 
If you live in the West Midlands area, give Pro 9 a call, they do complete rebuilds and conversions ala Singer-esque.

If all you need is a flange repair give them a call, https://www.pro-9.co.uk/contact
Another outfit is https://www.zhporsche.co.uk/
run by Paul Clare who are enthusiasts as well as an Indy garage.

Thanks David, worth a look at some alternatives. I am north midlands based so both are accessible.

I fitted a de-cat pipe and didn't really notice anything, I plan to fit a cup bypass pipe and I am told, that should be it. I wouldn't chase BHP without doing the manifolds as that's where the magic happens on these.
