Does the muffler delete give or take hp? Thinking about deleting the muffler already have a K&N CAI and a performance chip on the way for gains. I dont want to remove the muffler if it will decrease power and fuel.

 

Welcome to HF.

Do you have any idea HOW OLD THIS THREAD IS????????? READ: Old Threads/'Necro-Bumping'

Loud does not make power, a performance "chip" is outdated and have nearly nothing to do with reality, they simply trick the PCM into thinking things are different than they are and boost fuel and spark across a fixed rate.

If you simply delete enough exhaust pressure, the factory PCM tune will actually retard timing. Skip the chip, get your PCM Tuned. If you would like to discuss the topic further with our members, start a New Thread about it, this one is closed.
