These two make black slip on pipes for the Fat Boy Lo. Cobra has a 2in baffle and Rush 1.75. Being a previous Cobra owner I partial to them. But could I get away with the 2in with having to retune the bike?

 

without, sorry

 

Yes,,

I'll add the 1 3/4' Rush sounds almost the same as the 2''. but the smaller baffle should give U a little more TQ in the under 3kk rpm.

In 07 when I installed my Rush muffs they were just starting to become the Hot slip ons, probably 75% of riders just did the pipes only and the most Popular baffle sold size was the 2''ers..

The 1 3/4''ers should make a little better TQ under 3k rpm's with the added back pressure.

I went with the 2''ers cause I knew I was going to add cams..

I still have them cause I still think they sound as good as any and better than most pipes out there and they still look new after 5ys and 37k.
