I currently have a SI/DO exhaust no cats with the exit in front of the rear tire. I need to change it because I bought a body kit and the exhaust exit interferes with the body kit. Later I would like to install an eaton blower. The question is wich way should I go?
1.true duals with 2.25" tubing
2.true duals with 2.5" tubing
3.single exit with 2.5" tubing
4.single exit with 3" tubing
I am looking for performance I don't really care much about sound. Remember I do not have any of the cats. I don't really know if the cats issue affects the tubing diameter but i think that is an important fact.

I will greatly appreciate your input.

 

number 1. i believe, but you might wanna get some high flow cats on there

 

Why the high flow cats?

 

i just know when i took my cats off my truck lost power. and if your going to run new mufflers for power you would wanna do a straight through magnaflow or bassani or borla or something

 

Definately #2 if you're getting a blower... and you won't need cats.

 

I was thinking about this muffler maganaflow 12568 that has the x pipe inside. Even though the muffler is 2.5" in and out I was thinking to continue the 2.5" tubing to the inlet and at the exit install 2.25" tubing for now and when I install the supercharger i could change that 2.25" tubing to 2.5" for better flow. It is a good idea?

 

#2. 2.5 trues with a X pipe.

 

Thanks for the input guys. Any opinions on the magnaflow 12568 muffler?

 

it'll be a bit calm but a good muffler.

 

For those of you running an x-pipe, were they custom made or bought. I haven't found one through searching.

 

Must not have searched hard enough, they're everywhere.

Guilty. Im used to searching **** for the stang. Also I know these are noob questions, but this won't void a warrenty will it?

 

number 1 you don't need hi flow cats

number 2 true duals with X pipe X2

ebay is a good place for cheap X. Mine is magnaflow, but ebay has a knock off that is identical for $30.

 

Today I have ordered the magnaflow 12568. I can't wait to have it installed.

 

exciting isn't it?
