I had one custom made/built when I owned my IS200 sport,because I wanted the noise level as close to stock as possible it was made with a chambered back box.
Also bear in mind that the car manufacturers hands are sometimes tied by rules and regulations and have to try as much as possible to reduce weight,emissions etc etc resulting in cheaper looking/inferior materials etc
Congratulations and well done,always worth trying it yourself where possible with the added bonus of saving some money too(although not always possible lol)👍
Hi Phil there are stainless steel exhaust manufacturers that will custom make you one and you can tell them what you want,I did the same when I changed the exhaust on my IS200 sport
John,I think the answer to the question about the rear calipers is a yes, had same issue with one of mine(now sorted)and that's why I suggested Sean looked at the pins
