2003 Tundra Exhaust - Single or Duel cat back?

[rayvanzant]

I have a 2003 4.7 liter tundra and was wondering about changeing the exhaust cat back. Is there really much difference in power if I go the one cat back to duel exhaust compared to just going cat back with say a 2 1/2 pipe?
I am not looking to have loud truck,just little more power and gas milage. Thank You for the answers

I think dual looks better. I've never had a power increase that could really be felt just from changing exhaust. Keep in mind that a free flowing, less restrictive setup will give the most power in theory. My exhaust came from the factory coming off both sides of the exhaust manifold into a 2 into 1 muffler. When I put dual lines on I just put 2 single in/single out mufflers. The biggest difference in power was when I went back and put an X pipe in, it toned it down a little but it definately helped out low end power.

go with dauls you dont need true duals because the computer runs the motor yes it will give you power and looks but not enough for the cost of getting it done. i got mine done more for sound than anything else. if you want power get headers long tube headers and a high flow cat or gut the cat and get a dummy sensor to full the computer so it dont run rich.

duals FTMFW! Only thing I ever put on my trucks is side exit dual exhaust. Looks, top end power, and sounds really good too.

Now if you want loud I would go with flowmaster. 40 series single chamber muffler I have on on my 4.0 v6 and its pretty lound I can set car alarms off in parking lots when I go by lol

me personally, i like the duel cause it would make it easier for breathing, plus i think it makes it sound better

I have always liked dual cat-back, but just as long as the pipe is big enough the performance gains may or may not be there. You have to get the right setup like a Magnaflow performance exhaust, plus they do sound better. Much richer sound overall.

If you're doing the upgrade anyhow, go for the true duel cat-back, everything I've read says it will give you more power.

I'm clueless to this topic. What are the benefits to one vs. the other?
