I have noticed a performance difference when I need to mash on the pedal in traffic, but it's not a huge difference. The coolest part of the sound is hearing the turbo whistle. It does have a throatier sound, but if you really want a big change in sound you'd have to go to a 4". My buddy had his truck straight piped with the stock DP and it did make a difference just to have no cat and muffler. I chose to go with the stock pipe from the delete pipe back because I figured I could use the extra savings to do a DP tuner or TW chip. I really don't think a 4" will make much performance difference from what I've read. This setup cost me about $160. I could have gone to a complete 4" for about $320. Next is the 6637 mod when my old filter is due for a change. That should compliment the exhaust.

 

Oh shnikies, I might have misinterprited what he asked, yes the stock dp w strait dose make a difference in performance and sound but its not as good as a dp w strait. I thought he was asking if it was better..... Sorry for the confusion.

NOT at all. do it !!!

 

Yes, it saves money in the long run. My wife keeps asking me why I need new tools, because she sees the tools I already have in my roll-away.

I tell her I need new "diesel" tools. The ones I have in the roll-away are for gas engines. She and nods her head knowingly; then goes to the store for new clothes.

I figure the tools I need are the ones I don't have. The tools I want are the ones eveyone else has. Sound about right?

 

Nice write-up, very helpful!! Reps sent!!!

 

I like that "diesel tool" thing, Mooseman. My problem is that my wife is an organization freak. I don't think she minds the tools as long as they are compact and neat. If they start straying from the roll away, she questions why I own them. We don't have much space to begin with, so I have to use every available space efficiently. I stopped storing tools in my truck box since it was broken into. That really hurt.

 

Very nice!

 

Very nice write up and pictures you saved alot of people alot of headache rep rewareded. It is amazing how restictive they made these down pipes.

 

well you gave me enough courage to do it next week on vacation . now i need to make the woman think it was her idea an it will increase the milage
