Straight Pipe question

I have an 06 6.0, just put a straight pipe on and ditched the muffler. Sounds niffy but the truck seems very sluggish now and no low end power. Normal?

Re: Straight Pipe question

It should be just the opposite. Are you sure you don't have an up pipe leak?

Re: Straight Pipe question

Re: Straight Pipe question

I did a straight pipe with cat delete and I did loose a little on the low end. According to the butt dyno it seemed like there was just a little bit missing from zero to 30 but it more then made up for it everywhere else.

Re: Straight Pipe question

I doubt you can notice any real loss on a muffler delete...IMHO

Re: Straight Pipe question

I feel like the 6.0 is slow as hell on the low end to begin with. It could just be the placebo effect but if its really noticeable you might have a leak somewhere

Re: Straight Pipe question

My turner craped out.My truck wouldn't boost over 18 psi all of a sudden,no power, even on extreme. it would drive 100% better on the stock tune. Got smart bought an SCT last week.Its like having a new truck,a night and day difference.No leaks either just had the cab off experience,replaced everything/upgraded

Re: Straight Pipe question

Our trucks seem slower because the ebp (exhaust backpressure) sensor needs to see a certain amount of backpressure for the vanes in to turbo to operate properly.
