best exhaust

Which exhaust system gives the most hp and torque?

 

i heard that some of the dual exhausts take away power is this true

 

a free flowing muffler will give decent results. i like my dynomax super turbo muffler. really though...all you need is a muffler.....cut the old out/weld the new in.......essentially the same as a catback,just way cheaper.

 

Like Will said, any free flowing muffler

 

Not really. Sometimes on smaller engines it is best to have a little back pressure but you have a 4.0L so go for it! You will only gain power with that mod..

 

thanks for your help guys

 

So, as I read, Flowmaster and Dynomax seem to be the most popular choice in replacement mufflers. I have an 07 Double Cab, Long Bed V6. Looking for a throatier sound from the stock.

Would anyone have the part numbers handy?
