I have a spare exhaust on the shelf so decided to talk to a company based here about making an exhaust for the NSX. They are Custom/Bespoke exhaust specialists and come recommended by a quite few people I know. So just wondering from the exhaust gurus on the site as to what are the do's and don't of this sort of thing?
nice one mate
hopefully if i can get a car ... more of us are able to make of services like this over here
as always great to read and see about the hard work you put in about these cars
Many Thanks!
Just thought I would have a venture into it and see how it goes. I know after market exhausts can be purchased from other places but wondered if we could get a quality system made that didn't cost big £££ and obviously beings bespoke the sound and exhaust tips etc can be made to suit peoples needs.

Mark don't forget exhausts release power, not make it. :)Quote:

Make sure that you start with a big box/boxes, if not happy then get them to chop them and add pipe, and so on and so forth.
I went through this and spend lots of money, made a system only to be beaten to the finish line by the Crapini booming exhaust that sold for £ 400 beans.
No quality stainless exhaust can be made for that money.
Most owners do not even consider an exhaust until the OEM falls appart, then they either want a brand name and pay thousands for it, or buy a Crapini cheap and cheerful.
I could not be bothered with loosing money on an exhaust enterprise. perhaps times have changed, but I been there done that and it was painful.
PS A good flowing exhaust can liberate around 10BHP.
PS Tell them you want T316 stainless.
Mark is this they type of thing you mean?Quote:

I know they use 304, but will ask about 316.
