question on magnaflow sizing...

can you guys please give me your input on what size magnaflow is best to run, 18" or 14"? is the 14" to loud or sound alright. i just cant get an accurate sound clip for them. and what size piping 2.5 or 3? thanks alot!

 

anyone???

 

IIRC, in/our should be 2.5", not sure about the sizing though.

 

The rule of thumb is shorter=louder. I want to say our exhaust is 2.25 so if you go close to that size the muffler shop will bridge the gap and make it work.

 

bump... anymore imput?

 

+1 to the above. Shorter means less room to deaden sound.
Match the stock piping as closely as possible.

If you check out http://www.tacomaworld.com/forum/performance-tuning/20144-3inch-exhaust-pipe-too-big.html You'll see the second post talking about sizes and another muffler suggestion.

And if you look at http://www.tacomaworld.com/forum/technical-chat/19967-how-air-goes-thru-your-engine-basic.html it'll explain why.

Chris is kind of a stud when it comes to this stuff.
