About Us

The story of JT-Tuning as a mini-documentary. Use CC for English subtitles.

We are the number one sports exhaust manufacturer for Saab and Volvo cars. Our specialty is 3″ exhausts for turbocharged models.


JT-Tuning has deep roots in Sweden but now JT-Tuning is a part of Martelius Exhaust and produced in Finland. Martelius Exhaust has been producing racing and sports exhausts since 1982 and is using its know-how to further develop JT-Tuning.

Most JT-Tuning exhausts are made from durable AISI 409 stainless steel material. Manufacturing and fitment have been improved over the last 3 years.
