Ok, so i decided to install my Maxflo muffler bypass pipes tonight. I started with the driver side muffler removal, which went smoothly.

Then came time to "slide" the bypass pipe onto the catalytic pipe per the fabspeed instructions on their webiste... problem is that it wont slip on! It seems that the muffler bypass is just barely too tight too go over the cat pipe... ok, so there are some slits cut on either side of the bypass pipes, which would prompt me to think that you can somehow spread the bypass pipe to go over the cat pipe... the bypass pipe is too stong for me to spread using anything I could thing of (hands, screwdriver, etc...)

So, is there a way for me to 'slide' these pipes on by mylself? do i have to go to a shop for them to put it on for me? Or imaybe the pipe diameters are different across models and I got the wrong set? (i have a 2004 3.6L)

Can anyone help me? My car has only one muffler on at the moment...
Thanks in advance!

 

might be the wrong set...I have muffler bypass and they slip over the cat pipes easily...

 

Hammer time.

i made the slits a little longer also with a saw get a rubber hammer and knock the **** out of it

 

You could rent a spreader/expander tool from a shop or bring them to a muffler shop and have them spread/expand the tubing. I would think this approach would be easier to do and for future changes, more user friendly. Or you could get a hammer knock the **** out of it.

 

I went to Midas & they put it on their expander & it works great! i temporarily clamped them down w/ some u-clamps & the sound is great!
