I'm looking to change my factory muffler.what size is the inlet and outlet of the muffler?and does anyone have any tips on purchasing and or sizing.
anything would be appreciated
thanks?

 

I just put a Flowmaster Delta Flow 40 series on I love the sound

 

do you remember the inlet and outlet size?or the part#?

 

I believe the factory inlet & outlet on my '07 were both 3". I put a Magnaflow single in (3") and dual out (2.5" each) and it sounds and looks awesome. It's a little quieter than the Flowmaster, but with the K&N intake kit, at wot the thing screams like a banshee.

 

thanks.does anyone else have any sugestions on what brand to buy

 

If you're looking for the best flowing, I'd go with either magnaflow or dynomax ultraflo. They're both straight through design and give you a deep mellow tone. I can literally drop a baseball through my ultraflo. Heres the muffler I bought:

Flowmaster is always a good choice. It wont flow quite as well as the others, butthey sound great.They have a more aggressive tonethan the magnaflow or dynomax. If you have stock exhaust and dont plan on adding headers or highflow/removing cats look at the 10 series 1 chamber flow. Its louder than the 40 series, and flows a little better too. It wont be too much with a mostly stock exhaust, but with headers it would probably be too loud.
