I'm trying to decide whether I should go for dual or quad. Does anyone have any experience with trying out a quad-tip exhaust system for an F30?

Knowing if there's any discernible difference in sound will be the biggest factor. I'm looking for a deeper growl, so if significant, then I'll know to find a quad-tip diffuser as well in advanced.

The tips should not have any impact on sound all else being equal. There's a couple older threads on quad tips exhaust, just search. (Google search might even be easier to find them).

IMO, and this is IMO, the quad exhaust is just a fake M look and its pretty ugly on non-M cars.

@thejeremyman9 comments are spot on. There are quite a few threads on this topic with practical advice.

My humble opinion: get whatever exhaust best represents you and enjoy the ride.

absolutely it makes a difference but not untill you get to a tri-tip setup. dual-quad is the best but its so loud you likely wont like it. likely have to modify your diffuser to make it work though.

Had a quad M2 exhaust welded on and love it, I did have to modify the diffuser however but there were guideline on the back of mine to tell me where to cut and a Dremel made short work with that. You may also need to modify the mount that holds the sensor for the auto trunk lid but that's easy as well. With a catless downpipe, it is definitely loud but I don't think obnoxious unless your redlining your shifts.

If its the same system and the difference is only at the tip connection, the sound will be the same whether you go with dual or quad.

For the sound, get the REMUS catback. It is offered in dual and quad setup

We also offer quad diffusers for your car
