hey all, im looking to upgrade my exaust...im thinking about going to 2 1/2 inch or 2 1/4....is there much difference? also, im not sure about which type of muffler to get...there's magnaflow,borla,flowmaster,dynomax...tons...not, im looking to get the most power out of an exaust mod...should i go cat back? or from header pipe back? any help here would be hot!

 

btw...its a 92 4runner, 3.0 V6,5 speed....

 

2 1/4 Magnaflow 11225

 

2 1/4 from the cat back? or before the cat? about how much is the muffler and the tubeing?

 

cat back, it's what you should be running right now, so tubing costs nothing

 

so, 2 1/4 is whats running already from the cat back? and about how much is that magnaflow muffler that you mentioned?
