Long Tube v Short Tube

[Bharvey]

Okay well I have had my X runner for about 2 months and I wanted to do some performance upgrades

but I dont want to lose back pressure. So I was wondering what to and also should I change my Y-Pipe?

Urd headers

Will I lose any back pressure? Or just keep the same Y-Pipe with the cats

URD just finished test fitting the updated version of our Spec-U Equal Length Long Tube Headers for the 2012 and later Tacoma V6 with the air injection system.

The test vehicle was is a 2012 Tacoma XRunner COMPLETELY STOCK other than the addition of our headers.

Peak gain was 17 RWHP and 30 RWTQ

Max Gain was 22 RWHP at 3500 RPM and 34 RWTQ at 3430 RPM.

The most important thing to note is the Spec-U headers makes power throughtout the ENTIRE RPM range. NO LOSS IN LOW END TORQUE.

The truck is beautiful and I hope the owner forgets to pick it up!!

The headers have been cleared for production and we expect to start taking orders in about a week and shipping in five weeks.

These are the best all around. Depending upon where you live your emissions might require you to consider if you can deal with no cats.

This is true. I missed out the run before this one. Totally worth it.

will the headers be a direct bolt on to the stock y pipe?

Yes. Same flanges and all.
