i am ready to tune my G up now, since i never moded any car before, i would like to start with my Muffler and ECU, the question i have is, how much HP i can gain on Cobb AP Stage one map by just replacing the muffler? anyone has any idea? i know just for muffler its only gonna be 5Hp+, but how much it can gain after i use the Cobb Ap?

 

Good luck with the cobb

 

Don't expect much gains from just a muffler

 

Or the cobb

 

^ I agree with what they said. Wait until you have more mods before you spend money on a tune. Won't be worth it IMO.

 

You'd want stage 0 with just a muffler, but don't expect much gains, maybe 5-8 with both?

 

instead of spending the money on the cobb you can get your self a nice ingen or Stillen CAI and gain about 5 times as much power and change the sound at the same time.

Stillens been shown to get around 15-18 hp wherass UCLA Bruin dynod his ingen CAI at about 16 whp i think

Don't waste your money!

 

got it! I think i am gonna hold off the COBB AP first, but i am still gonna get a exhuast first, which one is better, between Tanabe and Fujitsubo? which one sounds better, which one gains more power?

 

They both will give you the same power if any bc they are axlebacks. As far as sound that is a personal preference... me I would go with the fuji bc thats like the old nismo exhaust which I loved but word of advice, they dont come alive until you add test pipes or hfc's if not they are very quiet

 

very helpful, thank you!
I think i am gonna go for tanabe, it sounds more deeper, and it looks better than Fuji.
i saw one Tanabe is only 599 on ebay, but on other websites it costs about 749.99, which one should i buy, both all new ones.
btw, what is test pipe? is that a down pipe?

 

or a magnaflow exhaust, I just picked one up for less then $500! yes a full cat-back for that price. Getting it installed tomorrow so we'll see the end result!

 

Check this out for a good deal. I'm sure HPA will hook you up on the Tanabe

i loved Magnaflow exhaust at first, i like the deep tone of that exhaust, sick!! but it only has full cat-back option, i am looking for muffler only, since this is my first time mod a car, i dont wanna replace too much stuff, haha. JUST INTAKE AND MUFFLER FIRST

 

Thank you, i will try to PM him.
BTW, how is your INJEN SRI works? i am trying to get these too, are those easy to install? does it come with full pic instraction? do you have any problem with it? and how many MPG are you running compare with stock intake?
Sorry i have soooooo many question to ask, just cuz this is my first time, hahaha, need grab as much infor as i can.

 

Don't know if I agree with that part.yes he needs more than a muffler,but I'm putting down 325 to the wheels,thanks to chamellion(professional tuner)but using the cobb with the loaded stock map.he was able to adjust the a,f ratio,big difference and way better throttle response(no lag).my mods are fi cat back,fi hfc's and stillen stage 3 cai.so I gained 15 whp, granted his gain will be less,but the car drives a lot better that's 100 percent.
