does anyone have a clue on how much power adding a cold air intake and flowmasters will give me. my exhaust is just a 40 series right after the y pipe and then a turndowns. cold air is an ebay generic. any help would be appreciated.

 

Doubtful the muffler alone is gaining much if anything, especially with the resinator still on the truck, assuming it is.

I would say from both 10 would be hopeful probably closer to 5.

 

Yea I'd have to agree with you. I think flowmaster is for sound, not as much performance.

 

Depends too on the engine you have.

The air intake seems to help the 4.7 more than the Hemi. I agree with just adding the muffler...I don't think it'll do much on either one other than sound better. Thing about the Hemi is that DC basically did a pretty good job from the factory to get 1hp/ci, so add ons don't do as much for it comparatively as other engines.

 

yeah its a hemi. no the resonator has been removed as well as the rest of the exhaust. my flow is right after the y-pipe and then thats it. no pipes or anything. just a 35deg. turndown.

 

I would bet on zero.

 

I'd also go for not much. If it makes you smile when you mash the gas, that's all that matters.

 

Can you legally delete the resonator and stay smog legal?

 

Yes, just don't touch the cats.

 

well, i got an air force 1 exhaust and a drop in k&n filter, made a big difference to me...but i am still going to get the k&n cai in a few months...still smoke GT's of the line, til about 55
