haha

Street Series Stainless Steel Magnaflow Mufflers are specially designed for premium power on import engine exhaust systems

go to summit racing and get a 2.5" muffler there

 

If you dump it, that could work out fairly well, but thats designed for ricers, hence the built in tips.

 

why dont they put ricers on there i cant just add coupling on the tips? well how about

Muffler(s) and tip(s) is all you need for a truck exhaust. Go to a shop and have it installed your set. The round body Magnaflows sound pretty good.

 

thanks darren ws6 as for the lt headers can i keep my stock cats? and is 2 mufflers better than one or just go w/ di/do and save money?

 

You cannot keep the front set of cats with LTs but you can keep the rears. Personally, I would scrap all 4 and go with Magnaflow 94106 hi-flow cats, and have the rear O2 sensors mounted after them. Dual muffklers with an X pipe would perform just a pinch better, but you can use a DI/DO so save some and get the same similar results.

 

what muffler is better 6x14 or 6x18 ????

 

The shorter the louder the longer the quieter. I would say the 6x14

 

thank you cant wait to get my set up
