This past weekend I finaly talked my buddy into helping me optimize my stock y-pipe on my 2000 csvt. I feel I must warn you that doing this is a pretty big pain in the a$$.
Altough it is well worth the effort.
There is a crushed bend where the two pipes off the headers join into the y at the rear flange of the y pipe.
Once you take it apart you will see what a major bottle neck this is .I know someone has pics of this.look under CEG photos on the main web site page and its under a heading of someone doing a 3L swap.
The 2000 from what I under stand and on my car has a three bolt flange. other svt produced mid year 99 and 98 have a two bolt flange .
This is the reason I believe the borla cat back is only made for 98-99 contour svt's due to the different flange. most aftermarket y-pipe give you a choice.
If you deside to go the cheap route like I did you will see what a pain cutting off the heatshield and welding the two halfs back together really is.
I was able to use a sawzaw a welder and file to do the complet task. but I could have used a grinding stone !
Once you over come the task of optimizing the y-pipe the benifit it well worth the effort you will notice a difference a big difference .I'm guessing a solid 5whp and 5 ftlbs of torque at the wheels.the car will have better throttle responce and it will get to redline a whole hell of a lot faster. you will really like this mod.
Before with my yokohama AVS ES100's I was lucky if i could bark the tires into second gear now with my current mods it SPINS yes SPINS the tires into second gear.
Sound difference is a little deeper but besides that theres no rasp or drone to note. good luck. IF you have the money buy an after market y-pipe if your on a budget like me this will take a few hours and it helps to know someone that can weld.
