I have seen many trucks v8s mainly that have dual exhausts, and i kinda want to do it depending on how much it runs


i have a small idea how, this is about how much i guessing where to begin by putting in a y pipe after my cat and running both pipes back?

or have a new headers put on, cause on mine, its both headers that go into one ,

obvisouly want my truck to still run right? anybody have vehicle knowledge how to properly do this?

No matter how loud you get your fuel burner to idle, it will never be louder than my power steering pump. I win.

A good starting point is typing 'f250 dual exhaust' into google. Kits commonly run from 200 - $400 and seem fairly simple to set up.
Word on the net seems to indicate this will increase your engine performance slightly and shift your engine's noises down in frequency, but again will not increase your chances of mating.

just run stacks they look way better but not 6'' one get like 4'' ones with a flapy thing on the top, oh and at work hear in Australia we make the side view mirrors for the new f250s they are fuking huge!

If he goes into the red neck part of town it will probs help!

He probably lives in the red neck part of town.

Do you have a emissions program in your state? Most do. That being said you have to basically be with in their guide lines when it comes to inspection time.

You could all ways get a cheep kit from JCWhitney and save the factory set up and swap them out to get through emissions test, then put the duels back on.

The basic idea to improve performance is to make the engine "breath" better. Splitting the exhaust will help but don't expect a huge difference...

I merged your 2 topics, you only needed 1 thread for the same subject.

If it were a high end performance engine I would say go for it, however its just the base factory engine so it will not run better or make a difference performance wise. Otherwise, it would have had dual at time of manufacturing.

Not true actually. Most manufacturers of regular passenger vehicles (in other words non-sports cars) tune the engine down to be conservative. Usually exhaust helps a lot more than you would think because the OEM exhaust is usually restrictive. The idea is to get all the exhaust out of the cylinder as efficiently as possible to boost power and it works for any engine. That's the main mod for the old Raptor go-kart engine and it boosts power a whopping 30% at the low end and up to 90% on the top end. Exhaust is always a safe bet for producing power on a stock engine even if it's a small percentage.

It won't do much good. If you want to do a dual setup then your best bet is to do a separate system with two cats in the case of performance. Of course, performance is really the only reason to do a dual exhaust that's worthwhile.

i really doubt he needs two pipes, ,my brothers 6.3l supercharged LS3 only has a single 3.5'' with twin tips for looks, its a performance form a very well know company in Australia. doubt his car need more then that!

i was just asking for a good way to do it and correctly and still have my engine running right

yes actually it is true. Were talking about a ford truck not a raptor go cart engine..
