hey, so i was wanting to put dual exhasut on my truck, but im not sure were i should put the Y pipe. I was going to take off the cat, and then just run pipe. Were would u put it? How would it sound if i took the cat off, and then put the muffler were the cat was a then split the pipe after the muffler so it looks like i have dual exhaust?

thanks

 

cut the pipes off before the Y and run 2 pipes that way.or cut it off after the Y and run a single 3 inch pipe.i took my cat off, it sounds louder without it, but check local laws about it or get a high flow cat put on. i had an S-10 with duals with flows and no cat and it sounded good[/align]

 

What do you do with the seperate 1/2" air line off the pump that goes into the CAT?

 

thats a good question. what do you do whith that?

 

i dont remember my trucks having that air line, i'll look at it this weekend and post my findings.i guess either cap it or leave it open

 

a pretty simple way to make dual exhaust is to remove your muffler and replace it with a split tail performance muffler, this will only leave you the work of removing the muffler and tailpipe and fabing new tail pipes

 

Did you happen to have a chance this weekend to look? b/c im going to be cutting my cat out this weekend and i was wondering what i might have 2 do if i have those puple lines.

I looked under my truck and this is what i c when im looking at the car, would i just cut the air line and then plug it?


thanks

 

I looked on mine and I dont have that at all. Try following it and see where it goes to, and if not sure take another picture.

 

 

yah thats the one, ive taken a coulpe pics of were it goes, im just on sure if i should plug it or leve it open, what do you think?
