Exhaust fitment on S550

[CommyO]

Hello all,

I have the MBRP Race exhaust system with a catless downpipe and it sags more than my huevos on a hot day.

I'm wondering, what are my options at this point? To get a shop to fix me some hangers, or weld it to the frame? The 4.5" tips also touch my rear diffuser.


thanks.

Have you tried to push the exhaust up as much as possible and tighten the clamps so it can keep it at that height?

Hello all,

I have the MBRP Race exhaust system with a catless downpipe and it sags more than my huevos on a hot day.

I would start with a comprehensive inspection. Get the car up on jack stands or a lift so you can get under it and look at things from different angles. Are there any dents or bends in the pipes that shouldn't be there (you can find photos of exhaust systems online for comparison)? If so, then you may have run over something. Are all the hangars properly installed in the rubber grommets? Are the mounts on the car still attached (check the welds/bolts)? Are any of the hangars bent or broken away from the pipes (check the welds)? Is the rubber all in good shape? Are all the clamps tight (soot around a juncture indicates an exhaust leak and loose clamp)?

If all these appear to be in order then you might consider taking your car to an exhaust shop and have them put some bends in the pipes to get them in the proper shape.

There's always that one guy. :-(

For the record, send those pics (if you have them) via PM--I don't want to see them.

+1 Recently went through this myself with the custom exhaust. I was getting bad vibrations at certain RPMs, so suspected exhaust contact the chassis. To be fair, I did ask the shop for maximum ground clearance since my car's lowered. Found a point in the exhaust where it had almost zero clearance with the chassis. I loosened all hangers, stuck a small crowbar to create some clearance, and retightened everything. The test drive showed no vibrations.

Get a different exhaust. Seriously, almost everyone has fitment issues of some kind with the MBRP, myself included.

Mine needed adjustments after going on, but since then it's been fine. I have the MBRP street but the fitment is the same.

The left to right balance of the exhaust is very finnicky on the Ecoboost Im told, which causes fitment issues.

In my real world experiencing of laying on the ground under a ecoboost, look at the hangers before the stock resonater. Adding a few washer there(there is 2 bolts on that hanger) to step it out will get both of the tips to move toward the drivers side of the car. As the next two hangers, before and after the mufflers, only really move on the rubber part of the hanger,not much adjustment on the bolts of those hanger, and as soon as you drive will move back and forth on the rubber. All aftermarket exhaust does not fit like the stock, and adjustment is always needed, but MPRB, regardless of ecoboost or GT always seems to be off.
