You guys think it's worth paying $50-$60 to swap my axle-back from 2.5" to 3". Everything else before the axle is 3" so my exhaust is bottle necked. Thanks guys

If everything else is 3", definatly upgrade. Bottle necks like that are what cause lost power.

 

if like you say, everythign else is 3 inch, go with 3 inch, you'll get some more power

 

The difference is...












wait for it










0.5" of diameter.


thank you, drive through.

 

You won't gain any power if the 2.5" is straight through. Unless you're already pushing 400+hp and the exhaust is the bottleneck.

Sometimes you just have to do things because you want to...not for performance. Just SAY they were for performance.

 

show me your set up one day at the shop and I can help ...

 

I dropped my Prodrive axleback section at the dragstrip and picked up NOTHING e.t. wise and just a tenth or two of a MPH. If I had seen BIG gains I would have considered getting a different axleback setup and tried to stick with 3" all the way. Don't know how much .5" diameter is going to make...
