I wonder if I went with the 28in case magnaflow with a built in X pipe and ran it to the factory location if it would drone like that. Im also a little worried the 28in case might be a little too quiet. The noise isnt what bothers me at the moment its the clapping noise almost sounds like theres a playing card at the end of my exhaust when I get on it which I think is because of how small the current magnaflow that I have on there is. I drive the truck from CT to FL every year and I just also want to make sure I dont get something that is going to drone so bad it shakes the truck. I dont mind engine noise at cruising speeds but the drone that some mufflers give is miserable. Right now I have the exhaust going 2 into 1 before the muffler going into a SI/SO 14in magnaflow and Im also trying to decide if I should put it back to dual inlet or leave it a single inlet and just get a longer SI/SO muffler.

Which DI/DO is it? Theres 2 I think ones a 28 and ones a 24in? Do you think part of the drone is just because its dumped under the bed? Or do you think it wold still drone if I had it exit out the side wheather it be infront or behind the rear tire? Which borla are you going to run? I was also thinking about doing a borla instead but wasnt sure which one I should get. I dont mind hearing the exhaust cruising down the high way I just dont want that annoying resonation drone that makes the whole truck vibrate and sound like you ave 3 15in subs just pulsating in the back seat!

Ya I think im going to give the DI/DO magnaflow a try. I just have to decide where I want it to exit. I like having it exit in front of the rear tire and wouldnt mind keeping it there or I was thinking of running it into the stock location. I dont want to do duals straight out the back so my other thought was to dump it under the bed. And ya cranking the torsion bars down was a terrible idea the truck rode like garbage the shocks that were on it were really bad to so that could have been a big part of it too but with them cranked back up and the spindles and new bilsteins it rides awesome. The bilsteins are a little on the stiff side but its almost a good stiff and they made the truck handle quite a bit better too.

Whats up guys I havent had a chance to get on here for a while been super busy with work and some other things so the truck hasnt gotten to much attention latley but figured it was time to give it some! I just put on new bilsteins all around and cranked my torsion bars back to stock height and put on some beltech drop spindles to go with the drop shackles in the back and it rides so much better. Now I just have to fix my exhaust. Once I put my LTs on and deleted the cats and had a custom 3in Y pipe fabbed up with a SI/SO 14in 5X8 magnow flow muffler and had it exiting infront of the rear tire with the stock SS tip it sounds awesome at cruising speeds and in town but once I get it on it it makes that terrible clapping noise and I just cant take it anymore. Ive pretty much narrowed it down to 2 possible solutions. I have a dynomax bullet thats been sitting in my garage for over a year thats pretty much brand new that I was thinking about welding in before the 14in magnaflow I have now, but theres another part of me that ones to try one of the magnaflow DI/DO tru X mufflers but was looking on some suggestions on what I should do. Im leaning towards the DI/DO tru x magnalow because from what Ive heard on youtube it has a pretty nice deep tone which is what im looking for and I also wouldnt mind if it quieted it down a bit not to much but a little quieter wouldnt hurt! So im open to opinons let me know what you think!

Truck looks awesome. Also wondering what drop you have on it!

I dont think I can run the 14in one because they dont make on that DIDO 3in inlet and outlet and my Ypipe is 3in. So Id have to run the 24in one and my only worry with that one is it will be too quiet. The next worry I have is currently my Y pipe is 3in 2 into 1 now and im kind of worried that if I go to a DIDO muffler with the 3in Y pipe that it might decrease back pressure and I will loose some throttle response unless the internal X pipe will make up for it no longer being 2 into 1.

Ya I know that feeling my current set up will set off car alarms. Definitley not the type of attention I want haha

Ya I feel like its near impossible to find the perfect set up. I was also looking at the borla xr 1s alot of people seem to like those too. But i cant even imagine how loud your truck must have been with those bullets and the cam, those things will definitley attract some unwanted attention!

Thats really good to know. I dont really mind quiet but I still want it to have some grunt to it too. Like one thing I like about my set up now is when I start the truck everyone around hears it and looks and it just sounds mean when your cruising down the highway but I honestly get embarassed to get on it because it almost sounds like theres a thin metal flap on the end of the exhaust or an even better way to describe it is a aluminum playing card flapping at the end of the exhaust tip its so annoying. I wouldnt mind my set up at all right now if it didnt have the terrible rasp. Part of me was kind of thinking that the stock SSS tip might have something to do with it? Or just that the muffler is too short. I must have listened to a zillion different sound clips of every muffler possible over the past few months and I just cant decide what I want to do. Basically im worried that if I swap it out for the tru x one and it ends up being too quiet than I wont like it and then ill be in the same situation. But I know what you mean about the bullets. I had one on my regular silverado with LTs and no cats and dumped under the cab and the drone was so bad it souned like I had a 30in subwoofer in my back seat just resonating it was brutal. You wouldnt happen to have a sound clip of the tru x would you? I know the cam and blower will make it sound different but a sound clip would still be good. Thanks for the help

I was just curious if any of you guys out there that run the DI/DO magnaflow tru x muffler the one with the built in x pipe have any sound clips of it preferably with long tubes?? My current set up now with my longtubes is no cats custom 3in 2 into 1 Y pipe into a SI/SO 5x8 14in magnaflow and I have it exiting infront of the rear tire with the stock SSS tip and it sounds good at idle and when cruising but it has a terrible terrible rasp everywhere else at first I thought it was an exhaust leak but I made sure everything was sealed up and its still the same. So I was going to try that DI/DO tru x magnaflow and just run it out under the bed. It seems like alot of people like that muffler I just kind of want to hear how it sounds with longtubes before I go out and spend the money. I just tried youtube but couldnt really find to much.

Does that NNBS intake manifold have square intake ports?? If so you need NNBS heads to use a NNBS intake manifold. I could be wrong but as far as I know all LQ9s have cathedral intake ports and the NNBS have square intake ports. Im pretty sure a TBSS has cathedral ports like the LQ9s which is why people swap them. Where as I think people that use NNBS intake manifolds swap to L92 heads or equivalent which have square intake ports. Basically if Im correct the NNBS intake manifold you bought wont work with the stock LQ9 heads you will have to swap heads too. The TBSS intake mainfold will work with the LQ9 heads. And as far as an X link im pretty sure you will need one to use the 4 bolt throttle body.

Ya i think ill just try the fuel filter first and see if they can tell me if my pump is good or not, I plan on having slowhawk retune it regarless in the next few weeks. But ya nelson does lock his tunes so I had to buy a stock PCM to have slowhawk street tune it, but I had this same dealership do a crank relearn after I put my LTs on and told them to make sure they didnt flash the PCM and they seemed to do a good job so hopefully they wont mess anything up. Itd be nice to not have to replace the pump right now even though I dont think they are to to expensive, but I drive from CT to FL every winter to race dirt bikes so Id hate to have the fuel pump go out on the way down there so I think if its questionable ill just have them replace it that way I wont have to worry about it.

Ya from what I remember reading it wasnt to big of a job. I have a really good relationship with a dealer down the street from me and Im super super busy with work and dont really have the time to do it myself so I might just drop it off there and have them take care of it. Now say it is my fuel filter causing the issues would that have affected my pump as well to the point where it would be a good idea to replace that at the same time? Id imagine its got to be one of those 2 things or something with my tune thats causing it.

Ya I will definitley look into that. How much of a pain is it to change the fuel filter? I think ive read on here that its not to big of a job. Any thing I should really pay attention to when I do it or anything I have to watch out for?

Ive only had the truck about a year and I personally havent changed the fuel filter yet but that also crossed my mind along with the the fuel pump. Is there really anyway to test to see if the pump is going bad? I have an aeroforce interceptor Im not sure if that will tell me my fuel pressure or not but if it did would that give me an idea on what might be going on?
