BMP has some old stock Hartge mufflers made by supersprint, list is like 950.00 and they are selling for 300.00, have around 6 available. The deal is they are listed for 90-95 525i but in the supersprint catalog the 90 535 uses the same muffler as the 90-95 525 so these Hartge's should fit my 535 using my fuzzy logic. Any thoughts/opinions on the Hartge or supersprint mufflers as to sound and/or performance?
thanks
