hi i think i have an idea of what i want to put in my truck.hopefully this summer if money isnt short. but tell me what you think
gibson heavy guage stainless steel headers
k&n generation II cold air intake kit\
flowmaster 50 series dual side exit exhaust system
kyb monomax shocks
addco anti sway bar kit.

how much hp and torque do you guys think this will add?
will i see a big difference in speed and acceleration

 

Performance wise, you will get way more out of long tube headers. The cooler the air flowing past your iat sensor, the more power you will have from a timing/fuel standpoint, but a lot of guys on here are of the opinion that the K&N does not produce enough to justify it's cost over a cheaper carburetor intake, and the K&N may cause extra turbulance because of it's filter location. Do a search on"fipk no more".I run a Flowmaster 40 1in/2out and like it a whole lot more than my neighbors do. I ran the Monomax shocks for a few miles and did not like them. They were too stiff for my liking, and I now have Sensatracs on there.

 

Shorties, will probably add about 6rwhp tops
Catback exhaust if its a 98 or later,figure on 3-4rwhp
GenII K&N willsee about10rwhp

You will only see the above #s if the trucks in good running order and has a 360/5.9 in it. 318/5.2 would see less.

 

I am running Gibson shorties.. the bolt on was as they said.. bolted right on and matched up to the Y pipe with no problems...Long tube headers will get you more performance then the shorties.....I have opted out of the K&N CAI PFIK... went back to the round AC... I'm not racing so there was no noticeable performance advantages.. but cost wise.. the round AC was cheaper.. and gave me the look I was after in the engine bay...I too ran the shocks.. again as per Mopowar.. they were too stiff for my ride.. I am running 40 series Flowmaster muffler and a magna flo Cat.. I have two complaints so far from neighbors as well.. but... the 50 series should be tolerable I think..I definitely would trust RM_Indy's figures.. but the 10 RWHP...from the Gen II .. I cant say I felt that much increase from my kit....like I said.. maybe if i was running my RPM's up there more.. it would serve its purpose..I would buy a cheaper round AC and save for a TB....but thats just IMO

 

If I got long tube headers I wouldn't go with the Pacesetters as the only time I've ever heard anything good about Pacesetters is on this forum and the same guys seem to be having one problem after another. Not worth it imo. This is why I didn't add headers. You can get 6hp some other way that is more reliable. If I got longtubes I'd go with the ones from I think it's Southeast performance. I don't remember for sure though. I'd probably just stick with a quality set of shorties though like those you seem to have picked out.

 

Only problem I've had out of mine were with the gaskets they sent with them.With good gaskets, the trick is to use thread locker,tighten them through several heat cycles, and then weekly for the first month.Out of curiosity,where did you get 6hp from?

 

RM_Indy mentioned it above i think Mo..... I think torqueing ANY headers through several heat cycles is the key...I've had headers on everything I've had with no problems..but... quality makes a difference to a degree as well....and gasket quality makes a difference on anything they are used.. I re torque mine every week... unless i do a long, long drive..where they get really hot... then I retorque the next day after they cool.... its just part of my weekly maintanance.

 

Level of modifications and what order you add them will make a difference in gains you will see. My guesstimates are based on avg et reductions Ive seen and software predictions.(1100+ passes since 96)

K&N 14x2.25 fipk first mod added (no cai in 96) and ets dropped .28 seconds or about 12rwhp.
Edelbrock TES headers/ypipe added next, only saw .12 seconds off avg ets. 6rwhp max (being generous)but thats if you have a ypipe also, most shorties dont include ypipe so you will probably see less with MP, Gibson or JBA.
Behind the cat, I tried flowmaster muff on stock pipework, no et change(cops on me for noise), edelbroke split exit catback gave .05 off avg etsand finallyMagnaflow 3" custom exhgave another .03 off avg ets.

Prior to my first time on a chassis dyno, software predicted 268rwhp based on ets running at the time. 2nd pull, put down 269.35rw.

 

Ya,Indy was talking about shorties. Dynos that I have seenshow alot more out of the long tubes. I just get a little bent when people bust on Pacesetters because they got a bad rep when people running the painted ones got cranky after they rusted out. IF YOU BUY PAINTED HEADERS THEYWILL RUST. I don't care who makes them. I guess, since I don't sell Pacesetters or own stock in the company, I shouldn't let it bother me.lol

Those headers John Mercedes sells are sweet, sure enough. Twice the price, but sweet just the same. They look like they're modeled after the Hookers that the Dakota guys run.

 

Is that the software you have on your site?
