Im about to buy ASM long tube headers opened up to 3", custom 3" mandrel bend x pipe and true duals to a magnaflow muffler dumped right before the axle from redaddiction. Im trying to figure out what this setup would sound like.

My truck is mostly stock at this current time. Would the 3" exhaust kill my performance? What do you guys think of this setup?

Are ASM's good headers?

Im just trying to do a little research before i drive from Houston to Arlington this weekend to close the deal. Let me know what you guys think. Thanks!!

 

3" true dual exaust is way overkill for a nearly stock truck.

 

Thats what i was thinking...

What if i got the headers alone? Would the 3" outlets on them even be able to be used on my 2.5" true duals?

My current setup is stock header, 2.5" true duals, magnaflow X-pipe, dynomax bullet mufflers and turndowns. Would i be better to stick with this than get his exhaust?

 

Sure, you can get adapters man.

 

Any eaxhaust shop has reducers that can have a flange welded onto them to bolt up to the header tehn reduce down to 2.5" exhaust.

 

Well, i will see if he will sell just the headers to me. I like the rest of my setup anyways and it is better for my truck since it would still only be 2.5".

Thanks for the help so far guys!!
