i dont know, because i was looking at them and ebay ones look exactly the same as any other ones, and for some reason i cant find any oem HR y pipes in ebay! and here in PR i cant find anyone selling it! i already have my z tube, and i want to do something else to my 05 G sedan, im between y pipes and coupe mid pipe but im leaning more towards y pipe because apparently they add a bit of power

 

These cars don't gain much for the money at all. You really need to go FI to get anything worthwhile. If it were say a later model, those things are so restricted that cheap bolt ons can get you 30-40 more horses for little cheap mods. First gen sedans came out of the dealer strong to begin with.

 

^+1^ I cant afford to go FI though

 

buy a Y pipe and a coupe middy, good combo.

 

Mrev2 plus plenum spacer will give you the best gains for the money. For about 600-700 bucks you can get close to 25 hp gains. I would also recommend getting an k & n hi flow filter (drop in) and a z tube since both of those items are under $120.

 

i got an 06 sedan 5AT and my dyno last week was 230 whp on a dyno-mite or max whatever the machine was lol, on a mustang dyno i get about 260whp and im an auto with just a CAI and Borla Exhaust so i know im over 300 at the Block so im happy but im not done yet :P lol still gonna do more.

 

I doubt your at over 300 given the age of our cars and the mods you have. I would guess somewhere closer to 285. Remember, auto put out 280 stock from the factory back in '05

 

the readings were from the wheel and considering at the wheel you lose between 10-20% (some reports of 30% or more on some cars) plus an extra lose of about 10/15% at the wheels since its an auto its safe to say im prob just over it or very f'in close

but unless i drive down to cali and use that new center that has a full wind tunnel/dyno setup like the manufacturers have to get the block numbers it will always be a % guess

 

holy **** all these post..i must have got 3 of them that actually helping me...i just want 25 horsepower at the block... im not trying to turn my g into a muscle car... its not a mustang... just a mild tuned dudes 25 hp to 30... wow crazy how 1 post can go all over the place..lol

 

Do the normal then intake and exhaust. Plenum cai hr y coupe mid and throw a tune on it. Sounds like it will do the job.

 

exactly MD Plenum spacer, Intake, Exhaust should get you the numbers you want the intake/exhaust dont need a tune since the ECU adapts but if you do all 3 especially the Plenum spacer you will need a tune.

 

lol thats too funny this hot girl i'm friends with her name is Dallas Dimone (Dallas D) i told her about your username and she's like lol that's weird

 

Headerback exhaust, Intake, pulleys, and V2 Intake manifold if you're lucky.

 

Yeah my name is Dallas Del Visco.

 

^ and you're a girl or guy?
