Overpipe with sway bar clearance? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

swift996 · 07-24-2013, 04:26 PM

Wondering if anyone can confirm running any of these over pipe options with a larger front sway bar? I'm running a 25.4mm Hotchkis front sway bar.

I'd like an accurate answer to this as well, but it seems like nearly every aftermarket overpipe has clearance issues with the subframe and/or bigger sways without stiffer engine mounts or grinding down the subframe to allow clearance under load.

Stock overpipe seems like the best bet for a while until the aftermarket figures out how to make them with clearance considering drivetrain movement under load with the stock mounts.

Isn't there minimal gains anyways with an overpipe? I'm doing the same though, leaving the stock overpipe and changing everything else.

I have the Hotchkis bar and the overpipe (Motiv) hits the swaybar. I had to use some wide washers to lower the swaybar mounts down slightly to clear. No issues so far.

Subbed for no fuss overpipe info.

I have the cusco sway bar. Wonder if there will be issues there. Any input? Planning on getting the Perrin overpipe

Do overpipes usually have an issue?

Nameless over/frontpipe combo with Hotchkis front and rear Sway bars

It's hard to tell if it's just the road or the overpipe hitting. So far, if it does, it's not frequent enough but i'll have to check.

I'm running the hotchkis sway bar kit and motiv overpipe with plenty of clearance.

EDIT: the more I think about it... I have a slight raspiness/vibration under load sometimes that may in fact be the overpipe hitting but I had this before the hotchkis sway bar as well. I need to get back under the car and take a look. I'm going to look into it further and see if there is a suitable place for a torque strap.

Mine was definitely the overpipe hitting the sway bar. I could see some of the paint missing on the swaybar and small mark on the overpipe. I only really hear it when it I give it a good takeoff in first or hard run in second, but it still annoyed me.

I had contacted Motiv and they mentioned that they only tested with the factory swaybar and not with a thicker aftermarket. I suspect that most companies did not test with a thicker aftermarket bar, therefore could be a hit or miss for many.

Motiv does great work with their products, so I do not fault them. Everything bolted up nicely. It could be variances in the cars themselves, something that I have seen before. I had maybe less than a quarter of an inch between bar and pipe.

Yeah most of these parts are designed with everything stock in mind. I've ran into quite a few snags where a design didn't have other aftermarket parts factored in. The product of such a new platform!

Anyone running a Perin over-pipe?

Nameless OP/DP combo here reporting no issues what so ever.
