so i bought a 06 PAC AWD 3.5 with 275K Km on it ... got a really good deal . Had performance issue ( sticky short runner valve flappers ) .

1st , gave it some sound and cheked the Cat to see if it is clogged up ... cat is just fine and flow is great . changed muffler for magnaflow 2.5 inch a the rear tip ... gave it some punch and hardly no sound . so i decided to replace the other muffler ( the one in the middle of the car ) with a magnaflow ... and wow , great deep sound and not loud at all ( i have 5 kids and use this car for trips and dont want a noisy exhaust ) and gave it some more torque . i can say by replacing the 2 pieces of exhaust , it gave me a quite noticable performance gain and economy. in canada we use l/100 so i went from HWY 15.7L/100 down to 11.7L/100 km - cruising speed of 120km/h.

tomorow i will do the injection cleaner and in a near future , i will remove the short runner valve system as i think the rubber on the flappers that close in the intake part are so soft that there is a lot of turbulence in the intake manifold and unequal air flow to the cylinders. WILL KEEP YOU POSTED !


Cheers

 

Question for you -- did the Magnaflow mufflers bolt in? Or do you need to cut and weld them in?

That's a pretty impressive gain you picked up on the fuel economy, and any extra torque is always a good thing.

 

THANKS Iam adding dule exhaust to my 06 3.5 diden't think about center muffler however i will change both now, should I add center muffler to new pipe as well?

 

Hey turbobass, can you give me the item codes and where you bought them from? could you also try an include some audio to hear whats it like. I like to idle "roar" of my 3.5, but if you added MAGNAFLOW, man I would love to hear this before I decide to go threw with changing mine.

 

Ok ill try to post vid of idle and wot this week.

 

Part numbers and/or where you purchased the 2 parts from would also help (i.e. Canadian Tire, Napa, etc)...

Cheers!

 

Hey turbobass, did you forget us???
