VRSF DPs subframe clearance
Hey, guys, after the long wait, finally got the DPs. Installed it the first tie and as I was tired and finished late, did not pay much attention to the clearance between the short pipe and the subframe. And of course I had a small rattle. Today I lifted me car to readjust everything and no matter what I do, I can barely get 1/8" of a clearance. Anybody else had this issue? Thank you!

The 1/8" should be fine but if it still rattles contact Tiago before denting your DP's. I have the VRSF DP's & 7" IC and didn't experience any fitment issues with either but I can say that space is at a premium for the DP's.

It seems like the overwhelming majority of fitment “issues” can be resolved by simply loosening the vbands and re-clocking the DPs. I would give that a shot before trying to beat the needed clearance into anything.

I've had my VRSF pipes on and off my car multiple times and never once had a fitment issue. As a fabricator in a past life, I know there is always a possibility that someone screwed up a pipes here and there, but the jigs they use to make the pipes and check tolerance before shipping them through QA shouldn't allow a set of pipes out the door that won't fit. Just because people don't know how to clock pipes doesn't mean they have fitment issues. Just means the person doing the install doesn't know how to install them. They just don't magically fit and our cars don't very in tolerance to the point a set of pipes will fit on one car but not another. So loosen the V-Bands and tap on the pipes to get them to move around a bit so they will clear without beating the hell out of your heat shield or your pipes.

This IS true, lol. I should say, I have heard more from VRSF people about fitment than other brands. However, VRSF does sell more than others so this may be expected.

I personally think VRSF provides a quality product for the $. Same thing as BMS. You have to be out of your mind to pay more than double for a set of pipes which do the same thing. Look at Robs post on the AR pipes and the shit welds on the inside of the pipes. haha The welds are shit but they fit well. Regardless, you ultimately should be happy with what you buy and if not, return it. No one is putting a gun to your head... Most of the vendors here stand behind their product because they all know what kind of @ holes we can be if they don't. |

I just finished installing mines, and I had no fitments issues, even with heat wrap.
I did bent the sub-frame heat shield a little just to give it an extra clearance.

Got the exhaust loose all the way back to the muffler and after a few tries, ended up friend holding the pry bar to keep DPs from rotating and got a little over 1/8 just under a 1/4' clearance.

Wish I caught this thread earlier. Honestly reclocking the pipes can generally resolve any clearance issues, otherwise the mid pipe hanger in the middle of the car can be adjusted to push the entire assembly over to the drivers side if you require more for whatever reason. I've installed about 12 of these new sets already and we compared clearance to the aFe, BMS, AR and MS comparison sets we have in stock and our short pipe has the same amount of clearance as the best of them which generally ranges from .25-.5" in that area which is more than enough to prevent a rattle. Using the mid pipe hanger generally provides another .25" or so. It's crucial to loosely fit the pipes with v-bands, bolts and nuts, align the flanges to the mid pipes, then tighten the v-bands followed by switching from side to side on the rears until both pipes are snug.
I'm always available via IM/PM/e-mail if anyone has any issues. I will say that I believe we are the most sold DP which is why you're going to hear about more fitment issues. The problem with offering a competitively priced product is that we attract more DIY installers who are less experienced installing a v-band to 2 bolt pipe which can result in more "fitment" issues where it's more of a clocking issue. |

On my personal car (my second e92), I had the VRSF and BMS. The VRSF pipe was touching the subframe. Best I could do it use the above techniques as well as put a large screw driver between the down pipes and frame before tightening them to the turbos. This gave me 3-5mm at best. I subsequently bought the BMS ones and they have a good 0.5" + of clearance. They bend in different places making this a non-issue. Note attached pics, same car, same day VRSF vs BMS. First pic is VRSF fit, second is BMS. YMMV, and perhaps they've improved the design, but the proof is in the pudding (and in my wallet). |
