Mr. Francesco

Hey guys, i have the dual r1 amuse and i have been noticing something.

If i am at a light in 1st gear, and i start to role and floor it heavy to take the S up to 9xxx and shift into second, theirs a pop sound. It doesnt sound bad, but i cant figure out why it does this. It only does it like this, any other time i 9xxx shift it wont pop. ex...(in 2nd to 3rd on the highway shifting at 9...)

I am thinking its the tone of the amuse, because it is somewhat restricted for backpressure. It also drones a lot.

Does anyone have any input to what it might be?...

Backfire?

Mr. Francesco

Its not backfiring, no flames. The exhaust tips have the normal black in them, and the bumper is still yellow.

You don't have to show flames to have a backfire. A small backfire can be contained entirely in the exhaust system and you won't see it.

Mr. Francesco

do you think this is backfire issue?

the S runs amazing, knocking on wood...

Bane

Sounds like a minor backfire... very possible especially if you don't have the cat in place

one question, is backfiring good or bad?

Sideways

BAD



This little split was from a backfire.....expensive and hard to repair. Don't let it do that anymore. Change your driving style in first and second or loose your exhaust.




This little weld was over $100

Mr. Francesco

Sideways, how do i change my style of driving to reduce this possible back fire?

Im just not going to do this move untill i figure it out. I need my car for the shows this summer.
