there seems to be an underlying controversey on intakes and exhaust. atleast i see it and im confused. when u get an intake an intake and exhaust you obv let more air in and more air out and cool your egt's because of less restriction. this is true. but my question is...some people say the more air you let in and out the more fuel you consume. thus lowering your fuel mileage but also helping ur enigne "breathe" better and increasing hp and tq. now if you read on most major exhaust or intake companies websites (say like k&n or flowmaster) they say the more air you let in and out...the more efficently your engine burns the fuel thus improving your fuel mileage and hp and tq and also lowering the egt's. i dont think companies with a reputable name like flowmaster or k&n would just b/s everyone to buy their product. they also have the proof of their dyno charts to show their claims of more fuel economy and hp. i also understand there are many factors that contrubute such as altitude/air temp/driving style and many others. i see how both sides of this can be true...but im not understanding which one is more true i guess. can anyone clarify this and give more "food for thought" for me and maybe some other people too?

 

my opinion & experience... the more airflow you have available, the better the HP & TQ up top... if you have lower exhaust backpressure you will loose low end torque... it's like a teeter-totter... one end goes up and the other end goes down. it is hard to get the best of both worlds....

 

thats also what im looking at...getting the best of both worlds...thats why i ask so many questions about this exhaust and that intake and the set-ups people have. im trying to find the best combo w/o wasting money and time on trying this and that.

 

afe stage 2 kit with the standard filter (small one) and aero turbine in place of the cat... then the muffler of your choice (preferably low restriction one)... should get you where you want to be... take advantage of my experimenting..

 

i think thats what ill have to look into. i bought the s&b intake off of triton. next on my list is a rokktech and an aero 3535XL in place of the stock muffler. then down the road i may put a free flowing muffler in place of the aero and move the aero up towards the down pipe. sound sensable?

 

did the S&B have an intake tube?

 

its just to the 90 in the tube. i need/want to find the tube with the straight piece going down and the next 90 into the turbo......or i need to gut mine. will gutting it do the same as buying a new one?

 

there are a couple... search for the blue tube or cool blue tube and also afe makes one for about $100 bux.

 

Hey Steve. Not breakin chops buy, I simply do not understand what you are saying.


We all agree that the more intake air, the better. How much back pressure can possibly be created by even a factory exhaust? The low end torque thing really baffles me. I swear my is like an animal off the line. I have a 4 inch downpipe, thento 5 inch the rest of the way.


Again my friend, not busting, just confused, I think.


Good luck with ALL our rides.

 

what I should have said was that for everyday driving, low end torque is lost... nail it to the floorboard and you should have alot of low end torque... boost builds really quick which will result in great torque numbers. it's the everyday driving that suffers. How many of us can nail it from light to light and can still afford to fill the tank?

when I had my mag only exhaust setup, my everyday driving low end power sucked... when I nailed it WOT, wow was the only word you could utter... it screammed... boost was right there, right now. adding the aero add a slight restricition to the exhaust flow... even though it is a straight thru design, it's only straight thru for approx 3" of the diameter. where it splits, its my opinion that it creates a tad bit of backpressure to the exhaust system. someone else posted an e-mail or conversation or something from an Aero Rep who stated that there might be an improvement in performance when mounting the aero where the cat was. this was in my opinon referring to a slight amount of backpressure added... adding to the part throttle low end torque. remember the exhaust stream is split in side the aero.

Personally, I think the happy middle ground here is to split the exhaus out of the turbo and have the aero/mag on one side and a striaght pipe or straight thru muffler on the other and use a exhaust diverter to switch between the 2... that way if the valve is closed, you get the side that offers the most backpressure, open the valve and now you have a really big area to flow exhaust gasses... the problem is controlling the valve.

anyways... enough rambling...
