Throttle body size
 

what is the 5.0 stock TB size? i am putting on my cobra manifold and my TB is sticking open some days so i might as well replace it. what size would be good with my mods listed below? thanks!

RE: Throttle body size
 

the cobra manifold opening is 65mm so just stick with that

+1 always match the tb to the upper intake inlet diameter.... in this case 65mm

sweet, thanks guys

I agree. 65mm is plenty and a larger MAF will help out, too. The stocker is 60mm. You don't have to get a TB as big as the opening of your intake, but you DO NOT want a TB larger than the intake opening.

How do you like that Pypes X w/ cats? I've been looking at a few different X's, but wasn't sure about Pypes quality....

Thanks,

Adrian

no complaints here. good sound with the combo. Little more raspy at higher RPM's. But i guess that is the x pipes for ya. the only problem i had was when installing it the catback system was too long for the x pipe so my guy had to hack off a few inches of the cat back. Otherwise it's a solid design, small cats on it:), totally different design from stock. I've only had it on for about 200 miles or so. But it's a nice touch. i notice more high end trq as well

I thought the stock was 52 mm.

well i am gonna take it off and measure it tonight so i'll let you guys know. 60mm sounds right though. i've heard that from a few people.

RE: Throttle body size
 

I've measured mine before. Stock TB is 60. Stock MAF is 55mm on the outlet side.

RE: Throttle body size
 

I would stick with a 65mm throttle body.
