http://www.motad.co.uk/product.php?prod=CB+SEVEN+FIFTY+F2N-F22+Retro Check these SS 4 to 1 headers out, and from real exhaust engineers (a black art). The only thing would be to get them from another Euro country except UK since 100% tax anything shipped. I found a couple more SS alternatives, but these guys may be able to stamp db limits on the pipes that would satisfy CA EPA stamp requirement. UK really has some nice job shop vendors, but the 100% UK tax man (to USA ONLY) can bite my #$%&. And look at these dudes (from where else, UK) 4 into 1 (50% more cost) and look at the FLAT 4 into 1 transition for maximum vertical (speed bump) ground clearance. BUT they are chromed and not Grade 304 (!) SS, boo! http://www.wemoto.com/bikes/honda/cb_750_f2t_f2v_f2w_f2x_cb_seven_fifty/96-99/picture/marving_master_4_1_complete_system/ Life is looking better, but I want the 20 year plus SS exhaust. That cleaning chrome exhaust pipes is for the birds, especially when rain comes down upswept pipes and I can't cover hot pipes with my cover. I was spoiled with BMW F650 ST which had SS no maintenance pipes. Chromed (only) pipes is a mob racket (CA DMV and OEM dealers)!
