Quieter Exhaust

My 98 Thunderbird Sport has a custom made all stainless steel exhaust, 3 into 2, straight threw, sounds great, but is very loud and I would like to tone it down a little.

I see there are 2 1999-2001 Legend TT mufflers for sale on a well known auction site, they look like they will fit, maybe with some adjustment, but is there anything else I need to consider? For example, will it impact jetting/back pressure etc?

Bike, will only run with the choke nearly fully on (running lean I guess), but runs well when the choke is on, but turn the choke off and dies immediately, the bike hasn't been started for 10 months so the carbs might be gummed up. I have removed the fuel tank and ran a separate fuel supply with fresh fuel, but didn't make much difference, so the carbs will have to be stripped. I mention this the mechanic who might be doing the work also said that I really should install the quieter exhausts before he strips and tune the carbs.

Another option I've looked at is fitting a DB Killer insert, but they seem to be 51mm, while my current set-up has ~40mm opening.

 

Yes, separate issue, which will be fixed hopefully.

Order if work is something like this.

1. Purchases new quieter exhaust cans
2. Fit them
3. Then take motorcycle to mechanic so he can tune and fix carbs.
