I have been following the powerstick threads and other exhaust threads closesly as I am exhaust illiterate except for the knowledge that freer flowing is better overall. I have looked at chambered exhaust on the classic chambered website and others sites and they look exactly like what I would like to have for my 07 5.7 Tundra. Since you own one of these companies and have worked for other major exhuast manufacturer I was hoping you might be able to provide some insight into the exhaust world (of powersticks) that I may not have gleaned from other threads.

1. On the classic chambered site it shows the peak hp and tq being increased, but I am assuming on a rod and carbed vehicle. With the freer flowing sticks on a new styled cammed and fuel injected engine could one expect the tq numbers to come up? I like the range of tq that my Tundra operates in and would not want to lose that, but I would like it to increase in that range, will the powersticks do this? It depends on how restrictive the OE mufflers are. The Powersticks WILL flow better than the OE mufflers, & you will gain some HP & torque if there is improved flow. Also, choosing the right diameter core mufflers is critical - dual 3" mufflers will be too large & you could lose some low & midrange performance. Stay with dual 2.25" or 2.5" mufflers.

2. I saw that you could make up to 40 inch sticks. What benefit or lack thereof would longer powersticks make or is it better to go with the 26 inch version? My rule of thumb is the longer they are, the better they sound. In 1969 when you checked-off the chambered exhaust option for a '69 Camaro, you got 4 chambered sections (2 per bank). The GM chambered systems made chambered exhaust sound legendary. 26" Powersticks are an optimum length for really good tuning IMO. The 40" Corvette versions also sound great, but won't fit on too many undercar systems. It does look like they will fit under a Tundra though. Your choice. I can also build them in lengths between 26" & 40" as well.

3. Is there any benefit to adding an x-pipe or an h-pipe to a true dual system containing powersticks? I prefer an H-pipe - I think it sounds better. The "equalizer" tube is a good idea on dual exhausts & helps equalize exhaust pressure between R&L banks, plus it can mellow the sound a little. NOTHING bad about doing an H-pipe. I'm not a big fan of X-pipes.

4. I have heard some say that an x-pipe will make a system brassy or pingy and only adds to the hp value on the high end of the system, would this happen to the powersticks? X-pipes add anywhere from ZERO HP to maybe 5, & the gains could also be an anomoly from one dyno pull to the next. A lot of people don't like the way X-pipes sound - they merge all cylinders into a single exhaust momentarily & I think they make exhaust sound a little funky. Some people think an X-pipe adds like 20 HP. I have seen enough evidence that totally disspells this.

5. Would an h-pipe really add to the tq value of a powerstick system or is a true dual system ok? You can add a crossover (H-pipe) & you still have dual exhaust.

Thank you for your time and I appreciate the knowledge you can enpart.

Also I would like to keep this thread geared toward chambered exhaust, so for those who would like to chime in please no flaming this system or adding what system you think I should get instead. If you have this exhaust and some of the answers please join the discussion. Again thanks for your answers.
