2.5" Custom Y-Pipe Installed

[Fletch]

First of all, thanks to Gabe (trd4life) that sold me this part. It needed some minor modification, a flange welded on the downstream end, a local shop did the installation and fabrication for $60 cash, took them a little over an hour.

It is cat delete with a flex joint about where the cat used to be. No CEL yet, been on the car since Thursday.

Initial impressions are good. It is noticably louder and the car just flies through the RPM range now, biggest improvement to mid and high end power. I think the car may have lost a little low end torque, < 3k RPM but I expected that. Another positive is the car does not seem to loose traction during hard acceleration as much. Perhaps that can be attributed to the high flow design and loss of some low end torque?

Glad everything worked out Fletch, sounds like your car is hauling ass ! I didnt notice any loss of low end tq. when i had the pipe on my car and I have the same mods as you pretty much. Curious to see your dyno numbers i bet your pushing 260+whp with your current setup.

Makes sense, I noticed the same power curve shift, granted with much lower overall numbers, when I put the 3" Magnaflow HF cat on my car. Lost some pop up to 3000 rpm, but it really goes after that.

welcome to the club of custom Y pipes!

can you take a picture of how yours looks?

i'd like to see how different yours is from mine.

Are there better y-pipes out there or are all of them custom fabricated? Whats the best size and how do you get it to still pass bs cali smog? Prices anyone?

Here is a picture of it on Gabe's site http://www.cardomain.com/memberpage/250047/8
Unlike the stock unit or jpp, mine does not have equal length runs from each bank.

I finally got a CEL, it was the P0420, Catalyst below threshold or something so I will need to look into installing an O2 sim. If only I had my own odbII scan tool, I could just clear it every few days as it seems to take a while to set the code. The other option I was considering is relocating the flex joint (currently where stock cat was) and welding in a high flow cat. The exhaust odor is quite strong now, not in the cabin but while idling and what not.

Does anybody have pictures of their custom units?
