I just changed my mufflers, I have vance & hines true duel headers with some sampson mofflers, I changed to v&h ovals. Do i need to have my sert adjusted? I think its a bunch of nonsense to have to pay $150.00 every time you do something with your exhaust.

 

I can't imagine changing those mufflers would cause you any issues.

 

I woulnt ,exhaust is after the fact.. But how much does back pressure play in tuning, each set of pipes are different with different backpressures????????????? see how it runs

 

That's the thing... How much difference in back pressure would there be between the two mufflers, if any at all? With any change in 'breathing' ability, it should be tested/adjusted to accomodate, 'after the affect' or not.

LOL, i have 9 more posts than eaheritage, I've got seniority! just playin witya!
GEEZ! I just looked at your join date too... only 208 posts in two years? yer kinda quiet aren't ya? There goes my seniority.

 

Yea, usaully not much to say, Im on alot over the winter usaully on a fact seeking mission or opinions. now i am curious about different back pressures.

 

If you have the SERT why not have it adjusted. Im sure thats what you bought it for. You already have the big cash invested. Might as well take advantage of it. Wish I had the coin to get one for my bike.
