Can you put big city thunder baffles into sportster factory exhaust, does anybody know what size/part #?

Thanks!

 

Not unless you go to the effort of completely gutting the factory mufflers. The stockers are already to restrictive.

 

I like the looks of the nightster exhaust, I was planning on getting a gutted set on e-bay and using those to replace my stockers. so you're saying it'll work with the thunder baffles? will my performance increase? will the baffles provide enough back pressure?

 

No, I'm saying that you'd be wasting your time going to the effort of getting a stock exhaust to the point of being able to put those baffles inside of them. Just get a cheap set of aftermarket slip-ons if you want those baffles. You'll get more performance if you open up the intake & exhaust.

 

right on, i'm planning on stage 1, I just can't decide on an exhaust. I want to keep sort of stock looks for the exhaust.

Thanks!
