straight pipe or not? personal experience and problems?

[louidoui]

I have a 4 inch turboback right now but its got a muffler still. Should I be worried about goin to a full straight pipe? What differences should I expect in power and mpg if any?

[01redcrew]

it will sound better and louder. Your mpg will only change for the worse because you wont be able to keep your right foot out of it

[louidoui]

Ha ha what about backpressure? Some say you can create enough backpressure in the turbo itself. This true?

[TheOne]

only difference will be the sound when you get on it.

what he said. You will not see a mpg increase only a slight increase in sound. The reason for that is because the turbo does most of the muffling unlike a normal aspirated engine say a gas V8.

More turbo at lower RPMs. Once it gets to 2200 RPMs it's all V8 diesel engine. Sounds amazing compared to with the muffler

I didn't like it at first but it's seriously grown on me.

I have a 4" turbo back straight pipe no kitty and I would not trade it for the world sounds Awsome no loss in power or anything I would do it for sure

Sweet I think i'm going to, I want to so bad. Only problem is I got 100,000 km still on warranty. I'm just hoping that the guys at Ford don't try to **** me warranty wise if any turbo problems come up in the future. Right now all I have is a mufler and 6 lift and 37s and they havent complained so I think i'm good. ps, I know this thread isn't for this, but have you noticed any positive things come from the zoodad mod? I live in Alberta with 7 months of snow almost so i'm hesitant

id really like to get rid of my muffler, but just not sure if its worth it.....I like how my truck sounds right now, but wouldnt mind trying a straight pipe...

[still runs]

id cut it out if you dont like it weld it back on my boys like it especially when i mat the peddle and you get that crackling roar @ 3000+rpm and you pin them in the seats another thing i picked mine up for $276 on ebay its a mbrp free shipping but i just looked and there on there cheaper now if your wanting a new 4"
