i'm putting a pfs dp on and i can't get the bottom back stud to go back on. it keeps hitting the bend in the dp and there seems like no way it can go back on. i was able to get the other 3 studs on easily. is this okay? thanks, nick

nope...it will eventually leak, like mine...

thanks legend. does anyone actually own the peter farrel supercars dp? when putting the nuts back on the studs i can't tighten down b/c the washer part of the nut is hitting the weld. i already grinded down the nut but there is still a gap b/t the flange and nut. nick

I don't have that DP, but I know what you're talking about. Pull out the stud that's caddy-corner to the stud you're having trouble with. That should allow you to tilt the dp away from the problem stud enough to get the nut started on that stud. Once you've got it below the level of the DP, you can put that other stud back in through the DP hole. That should allow you to do it.

Hmm, well unless its a TII which only uses 3, no its not okay. Its going to leak, maybe Mr. PFS himself can help you out.

Garfinkle put a pipe on last week and he used allen bolts (ss I think) he cut a short tool to install ,his car is the same with no leak and the bolts will remove easy

Allen bolts are a good idea.
I have a PFS dp and always stuggle getting it on and off. I know exactly what you are talking about. I had to do a little grinding as well.

finally got my dp on. i was very suprised as to how easy it was to take the pre-cat off. after soaking them all the nuts and studs came out very easily. i was glad i decided to do this myself. thanks for the help rikki but since i bought it used it didn't come w/ bolts. i ended up grinding the washer part off of the bolt. i took it down to the actual hex of the bolt and they ended up going on smoothly w/o hitting the welds. thanks for the reply's, it was good to hear others had to grind the nuts or use allen nuts. thank god(or jason) this form is here. nick

Glad to hear that everything worked out. I have the PFS DP also and had zero fitment issue with it. No stud needed to be removed either. Performance gain is great and the install went smoothly.
