Small power boost

Hello all!! This is my very first automotive forum so bear with me please.
I have an 05 4.7l V8 and I’m looking for ideas/opinions on power increase, nothing huge but I’ve planned for CAI already, just looking for a few more tips? Thanks in advance!!

 

Open up the exhaust with a cat-back system. Then headers. Then gears. I wouldn't bother with a cai. Just my .02

 

The CAI won't make a noticeable difference on its own but it will certainly make it sound better. On my 2006 Double Cab I wen't with K&N 77 Series CAI paired with a Borla Dual Exhaust and it sounded great. Couldn't tell if it had any performance benefits since I put big rims and tires on at the same time. I was gonna install headers at one point but the quote I got for the install was almost double what the headers cost so figured it wasn't worth it.

Maybe @dirtydeeds has some advice since he has worked with Tundras for a while.

 

Awesome!!
Any particular brand of headers you’d recommend? I do all my own labor so the price shouldn’t be too bad.

 

Flex-a-lite 775 electric fans, I used them for 8 years on my '05 and they were awesome.

 

Welcome from CO

 

I think Doug Thorley and JBA are gonna be your main options for headers. Can’t remember which one had better reviews when I was researching them though.

 

@dirtydeeds sells upgraded fuel injectors. From what I’ve read they make a noticeable difference in the way the engine performs. Without doing a full search I want to say they were 12 hole injectors.

 

Thanks for the mentions guys!!

Y’all certainly tagged the right Company. We have upgraded injectors that take the stock 4hole and replace with our own 12hole.

We also developed a true 4into1 collector long tube header with jba. And are the inlyncompany to offer a bolt on mid pipe and or a bolt on race system to perfectly compliment the headers.

Gearing is a big difference as well.

Once all of the above is complete, we can also custom build a 1 off turbo system that has so far added 100hp to the rear wheels, and this is before the addition of e85 which was a huge increase in performance.

Please feel free to give a call for more details and if we can help in anyway.

Save your money on that intake. At the most just put in high flow filter and put your money into something else.

 

I appreciate all the info, I will have to look into some of the options dirty deeds has!

 

I received a small power boost on my '02 4.7L by adding JBA short cat-forward headers, I also run standard height tires with an LSD in the rear. Everything else is stock.

 

Hello, everyone. I'm new to this forum, as well as to the Toyota world in general. I have a 2008 4.7L Double Cab 4x4, as of a couple of weeks ago. I was looking to install a Borla cat-back system on it, but a rep at Borla told me they don't seem to make a system for my truck. Given the similarity between my truck and that of the OP, as well as the general subject matter in this thread, I'm hoping someone here can offer some quick guidance. Do they in fact make a bolt on cat-back system for the 2008 4.7 double cab, or would, say, a 5.7 system need to be modded to fit? It just seems to me that they, in the interest of simplifying mass production, would route the two systems in the same manner.

 

The 4.7 and 5.7 is a different exhaust. Slightly different. But different.

We build a direct bolt on catback for 07-09 4.7 Tundra’s. Pipe sizing is appropriate for the displacement. Routing is stock. And it uses the stock odd ball diameter tailpipe.

Check out standard systems on DirtyDeedsIndustries.com anything listed for 5.7 can be made for a 4.7 with engineering that is specifically for a 4.7 so it drives right.

Thanks for the mentions guys!!

 

Thanks a lot for the info, dirtydeeds! I'll definitely check out the site. I guess the only question left to ask is whether I'll get my exhaust done dirt cheap.

 

Haha. I know, I’m an AC/DC fan too
