Throttle Body Spacer: do they help with gas mile and performance worth the buy?

LT's True Dual 2.5" piping x-pipe to a MagnaFlow Muffler then to dual side exit just before the tires: Been word that its good for performance but hurt gas mileage any info on this?

Royal Purple: i dont think it will give u 10 HP so do yall? anyone tried it

 

Don't waste your money on the throttle body spacer. There are no benefits. I like the exhaust idea. It will give you better performance and mileage....if you can keep your foot out of it. Royal Purple is good stuff but the 10 HP claim is too much, IMO. You'll get 5 HP, if that. If you're willing to pay the price of Royal Purple, go for it!!!

 

Actual hp gain from Puprle...not sure on numbers but goin from Mobil1 to purple i can feel a differance set of the pants for sure.
I've gone from one to the other a couple times and it always feels stronger with the purple in there.

 

The throttle body spacer is not worth it. The exhaust idea sounds good. It will help performance and not hurt your mileage like BlackLM7 said.

 

I also agree on the tb spacer I bought it before I found this site, and i doesnt do much except whistle. Royal purple works not sure how much I gained but good oil.

 

Yeah, the whistle from the spacer sounds kinda cool, but doesn't do much, if anything at all... The exhaust is going to help out, but you will always have your foot stuck in it to hear you exhaust! If you want some better breathing--get a ported TB or step up to an 80mm. I noticed immediate results when I put my 80mm in--first gear is absolutely useless!

 

Only way to go on a spacer is if its got two lines hooked up to it

 

what kind of LTs are u getting? im going with the same set up, im looking at pacesetters and hoping that the exhaust shop can hook those up to the stock piping without any trouble.

 

ok going to do away with the throttle body P.O.S.
Pacesetter Headers yea what im looking at going in to true dual then in to cats then to the x-pipe out to magnaflow mufflers then having them come out right in front of the rear wheels
Also get a trans servo its worth it i installed mine im getting like 1 to 2 mpg more im serious it shifts better and its good for the trans less clutch wear its a great thing for 17 dollars
