I saw this post and was surprised not to see a 2.25" recommendation. When I originally got my TRD header and cat-back, the TRD tech/engineer I spoke with said the 2.5" option was for non-header applications or for when they also installed the supercharger. I explained that I pulled a 3500# boat and didn't want to lose ANY low-end torque. He insisted that I get the 2.25" cat-back in combination with their header to keep the torque curve similar to stock. The most obvious benefit after the upgrade was that a previous flat-spot in second gear on my automatic-equipped truck seem to be replaced by much better acceleration. <img src="/forums/images/graemlins/kewl.gif" alt="" /> Brew

Getting the Wheeling Fever

Brew and others, So what would you recommend for one who doesn't have headers and does have a SC? Also, I'm curious if you'd recommend headers along with the SC to help it breathe? IOW, What would be the best combination for a 3.4L T with a SC? <img src="/forums/images/graemlins/evil.gif" alt="" />

From what I've heard you need the headers and can open it up to 2.5". The SC will give you plenty of low-end. <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> However if I wanted maximum grunt, I'd probably stay with 2.25" and the header.

He bought my wheels and tires so I know he still checks the boards. Hey William, what do you think?

Need a Spot

I'm currently running JBA headers stock pipes and a reverse flow turbo muffler (Dyno max clone). I pulled the fuse for the ECM after installation and after a hundred miles or so of driving am very impressed with the difference. So impressed I'm in the middle of installing LSD to help with the spinning tires. The exhaust is a nice low berble. I had a bad seal where the stearing shaft went through the fire wall. I was surprised at the woosh sound the new headers produced. So much so I checked a couple of times thinking it was an exhaust leak. I fixed the seal and the THHHHHHHHHH sound is all but gone.
