April 12, 2007I am thinking of changing my K&N setup that sits in the stock filter box, for a FIPK series 77 intake. I have been told that using the new intakes tube, will cause a lot of loud noise, i want to ask those that know this, " how does the sound from your engine compartment change when you install one of these ? I have a nice sounding exhaust and want to keep hearing it. This guy at the 4X4 store said it would be better to use your stock intake tube with the FIPK series 77 to cut down on the noise. I thought the new intakes, intake tube, was where more power came from. Please comment on this so i can make an informed buying decision. By the way, my truck is a 2003 GMC Sierra with a 4.8 engine.
April 13, 2007Well, all I can tell you is what I know. I have a K&N FIPK II on my Dodge 4.7L. My exhaust is Flowmaster 40 series SI/DO. When I am cruising down the road the intake is not noticeable. I have also never been in a vehicle next to my truck, while going down the road. What others hear, I do not know. I also drove with the K&N drop in filter for quite some time before getting the whole schebang. I'd swear I probably got better mileage with just the drop-in-------possibly. The only times I can actually hear the intake is on first start when cold, and turning the truck off. I also don't see how you can use the factory tube with the K&N setup. On my Dodge, the intake replaces all the factory setup---no way around that. By the way, mine is the all plastic, and I think yours will be aluminum air tube. There may have been flaws in the earlier makes on both, but I think this is a non-issue now. I like mine, and also have a bored out throttle body to go with all the other 'air-in, air-out' mods. Good luck Bert!
April 13, 2007Thanks Redrider, i went to get a picture and all my text i wrote you vanished, oh well. I said in it that no use buying the setup and use the stock tube. the store guy doesn't have on on his truck, he has a lifted, and i DO MEAN LIFTED Dodge diesel. I had a truck muffler put on and it only had a SI- So and the guy that did it put the tailpipe in the stock location. It was one of those long heavy round mufflers that sounded great, when you tromped on it going up the freeway on ramp, but cruising through town or even idling it was too quiet. I used to put my passenger window down when going up the on ramp and trying to hear what my exhaust sounded like reflecting off of the sound wall, but it just didn't satisfy me. I went to a different muffler shop and the guy there young guy and new dad a few days before, changed it out for my flowmaster delta flow 40 with 3 inch in and dual 2 1/2 out, BUT, angled down at 45 degrees behind the tires. I wanted the Big stainless tips, but all he had were Magnaflow tips with the word magnaflow engraved on the ends. They really look classy and don't corrode or tarnish like chrome tips. This guy was a real muffler install genius, he was just a natural and when i slipped him $ 20 while he was in the pit working on my truck, he did an extra NICE job on it. I had gone to Harveys casino in lake tahoe just to pass time and ended up winning $1,180 in a slot machine with $ 2 invested. anything under $1,200 doesn't have to get reported for taxes so i spent the $400 to redo the exhaust, tipped him $20 for his new babies bank account, he worked on my truck as if it were his own, and does it ever, sound NICE !!! here are a cpl. of pictures. Oh Yeah, he designs his own muffler hangers too.

Boy, trying to go from one page to the next to get a picture and then going back, back, back, to get to the post is frustrating when the pages have to be refreshed each time, and then lose the text or picture.
now let see if NIKKI shows this time
April 14, 2007Truck looks good. I like the location of the tips.
April 14, 2007Thanks, they have their own unique sound pointed that way too.
April 14, 2007That's an awesome story Bert! Way to go! Yeah, I see more tips located that way every so often. You truck looks great no matter what it sounds like Bert. Just seen your post and had to put in my experience with mine.
November 8, 2007I ordered a K&N FPIK cold air intake and having it installed on my truck tomorrow ( friday) I have the choice of going with either the plastick black tube or the 77 series polished tube. I really like the way the 77 looks but is one tube (plastic/polished) better that the other ? The dealer mentioned that he thought the plastic tube would keep the air cooler than the polished tube, Anyone know if there IS a difference ? it is going on a 2003 GMC Sierra with a 4.8 and flowmaster exhaust, 3 inch single in with 2 1/2 inch dual out, if that makes any difference.
