What to really expect from exhaust and CAI?

Hello all, forum looks like a good place. Anyway, Im looking into putting both on my 08 TRD sport, but between all the info here, talking to some shops and tech support at autoanything, Im pretty lost.


For CAI, was thinking K&N, then vorla, now wondering about AFE or URD.

1) there doesnt seem to be a consensus on what you actually gain from one, so what should I expect?

2) Do I need a MAF sensor?

Id rather not spend about $300 for a CAI, and then have to drop $200 for the MAF sensor, especially for no real performance increase.


For a catback system, there also seems to be disagreement as to whether its just for sound, or whether you gain HP and/or mileage. I was looking at Borla or magnaflow

3) what can I really expect with a catback system?


4) if they are worth it, can avoid any potential hassle by just going with TRD through the dealer?

thanks

 

took the words out my mouth. I have all of these.

 

any problems with a check engine light from any aftermarket intakes? i had a check engine light after i installed an aem intake on my old sentra. Would you run into that on the tacoma at all?

 

Lol, yea hopefully that was all it was. I was just wondering if anyone had any probs with that. I think i was getting an engine code for the O2 sensor so it coulda been my fault

 

no problems at all after Volant CAI, DT header, and DT cb exhaust installed.

 

You like the dt exhaust? i just bought the headers, need an exhaust now

 

its probably the best sounding exhaust ive heard on a 2.7L. The headers are supposed to do more as far as performance is concerned.

 

thats awesome, yea i'm just looking for an upgrade from stock

 

I had the TRD CAI on my truck for awhile (installed by dealer) after a few months my check engine light came on and I took it back to the dealer. They had it for several days and did several different things but eventually the solution was to remove and go back to stock. At least the Toyota dealer refunded parts and labor to me in full. I would like to put one on but since I have failed once I have decided to just stick with stock.

 

these are the reasons its starting to sound like keeping it stock is best

 

what was I expecting? Maybe the claims made by the CAI and cat-back companies to not be complete BS and actually accomplish nothing but causing problems

 

and fyi, the camaro/mustang 6 cylinders are pretty bad ass, and likely will be just about all GM/Ford is producing in a few years

 

sounds like the chinese herbal remedies that say they help with every ailment known to man

 

so around a grand to notice anything?

 

pretty much just a bunch of noise. The best thing you can do is get a URD MAF CAL. even if you are bone stock this will still give you some more power.

or look into headers, they are pricey but worth the money if your looking for performace upgrades.

interesting, maybe better if I just spend the grand on my muscle car and just keep the tacoma stock

 

Installed K&N and Banks cat-back, intake gave it better throttle response and a few more HP, the cat-back is cool sounding with a tad more power, not huge, but it's noticeable, BUT, the CAI made the truck run too rich. MPG took a dive, I pulled it off because i'm moving right now and needed the stock MPG's. Gadget at URD says the MAF calibrator will correct the problem, so I will probably get that and hook my lapper up to it and fuck with it till I get what I want. The last thing will be some shorty headers and that will get about as much out of that engine without an SC.
